So, starting at the top and ignoring the Kit Modules for now;

Class Specific Kit

Epic Romulan Imperial Navy Profession-Specific Kit Mk XV [+Pla] [Armor] [CritX] [Regen]

Available from the Uneasy Allies mission in the Iconian War story arc and available for each class/profession.

Armor

Epic Romulan Imperial Navy Combat Armor Mk XV [HP] [ResAll/HP]

Available from the Uneasy Allies mission in the Iconian War story arc.

Shield

Epic Na'kuhl Temporal Operative Personal Shield Mk XV [Cap] [Cap2]

Available from The Temporal Front mission in the Future Proof story arc.

Weapons

Very Rare Na'kuhl Temporal Operative Assault Mk XII [CrtH] [Dmg]x2

Available from The Temporal Front mission in the Future Proof story arc.

Epic Plasma Long-Range Assault Minigun Mk XV [CritD] [CrtH] [Dmg] [DoT3]

Not available from a mission but you might be able to buy one on the Exchange or from the equipment vendor on the Romulan Flotilla, New Romulus Command, Dyson Joint Command or Delta Quadrant Command. There are very good alternatives such as the Plasma Repeater Pistol which is available from the same locations as the minigun, however, the reason why I chose the minigun over the repeater is because the secondary firing mode on the repeater seams to be bugged at the moment.

Explanations

The reason why to go for a plasma weapon is the extra 20% plasma damage given by the Romulan Imperial Navy Profession-Specific Kit module and you get a chance at applying a plasma DoT for extra damage.
You equip the Na'kuhl Temporal Operative Minigun weapon to give you the 2 set Na'kuhl bonus for +2% critical chance and +30% critical severity. The Na'kuhl Temporal Operative Personal Shield has a great bonus called Time Slip which makes you immune to all damage for 10 seconds when your shields drop below 10%.

Another great ground set is the Gamma Reputation set; The Concerted Resilient Personal Shield, Concerted Polyalloy Weave Armor and Concerted Inhibiting Polaron Pulsewave Assault rifle.

The set powers for the Gamma ground gear is;

Set 2: Concerted Reinforcements

To Team and Self (stacks with teammates):

+10% All Weapon Damage
+10 Kinetic and Physical Damage Resistance Rating

Set 3: Concerted Resilience

To Team and Self (stacks with teammates):

+10 Energy Damage Resistance Rating
+5% Maximum Hit Points
+5% Maximum Shield Capacity

Another great set, particularly for tactical officers, if the rest of the team aren't using the Gamma ground gear, is the full armor and weapon set from the Survivor mission in the New Frontiers story arc which gives bonus of 10% critical chance, 20% critical damage, +25 kit readiness and +25 kit performance.

Engineering Kit Modules

The first two modules you equip is personal preference, although I always have Mine Barriers in my first slot. You could go for the standard Chroniton Mine Barrier or the Cloaked Mine Barrier from the Gamma reputation. There is also a Security Officer duty officer which gives a chance to hold enemies caught in the mines.

Another module you could equip in one of the first three slots is the Sabotage kit module from the Kelvin Timeline lockbox which disables enemy weapons within 30m and causes all foes within 15m electrical damage. However, if you find you need more firepower you can replace Sabotage with the Seeker Drone and equip a Fabrication Engineer duty officer which gives a chance of beaming in additional drones and an Armory Officer that can reduce the cooldown. More about duty officers below.

The third kit module you should equip, which I consider I must, is the Engineering Kit Module - Neutronic Mortar Mk XII from the Delta Alliance reputation, a really good damage long range mortar. Alternatives would be the Photon Grenade Launcher (23c.) or the standard Quantum Mortar if you haven't unlocked the Delta Alliance Tier 3 yet. The Explosives Expert duty officer has a chance to beam in another quantum mortar.

The Forth & Fifth Modules

The forth & fifth module should be a module that will help keep you and your team alive. I recommend using Photonic Barrier to give you temporary hit points and damage resistance & Nanite Medical Generator to heal and give more resistance, but here's a list of modules that come highly recommended by our fleet admirals;

Science Kit Modules

It goes without saying, the first kit module you should slot is the Medical Tricorder. This will heal you or your target, remove expose effects and give you damage resistance.

The second kit module you should slot is Throw Regenerative Nanite Canister Miracle Worker module from Dilithium Store. If you haven't got access to that, slot the Triage kit. Similar to the tricorder, Triage will heal and give damage resistance but is an area of effect ability.

The third kit module should either be Paradox Bomb which you can get from the dilithium store once you've spent at least 27 points in the Temporal specialisation. Or you can use Gravitational Juncture which you can get from the Tzenkethi or Infinity lock boxes. Both are fairly similar in that they both pull enemies towards it, but, the Gravitational Juncture reduces outgoing damage from enemies and reduces their damage resistances and run speed and the Paradox Bomb disables sprint and roll and also deals physical damage to all enemies in a large area. Which ever one you use it will help to herd enemies together to keep them in one place long enough so you and other team members can focus fire on the whole group.

The forth and fifth modules you should equip are for pure damage. There are differences of opinions, but here's a list of recommended modules from our fleet admirals;

Tactical Kit Modules

The first two kit modules you equip are for boosting your team. The Coordinated Synergies kit from the Gamma Task Force reputation provides team-wide boosts to All Damage, Running Speed, and resistance rating while the Motivation kit from the Xindi & Infinity lockboxes provides your entire team with an increased chance to critically hit and any successful critical hits will also heal them for a small amount.
Standard alternatives would be Rally Cry which is available from the Fleet Spire and R&D, and the Overwatch kit. Both will provide some healing, buffing and damage resistance for you and your team.

The third kit module you should equip is the Graviton Spike kit from the summer event store. Graviton Spike enhances your weapon fire with charged Graviton particles to generate a singularity on impact. Enemies caught in the singularity's range are subjected to Kinetic damage as they are pulled toward it. While the singularity dissipates almost instantaneously, residual Gravitons slow the movement speed of affected enemies for a short duration.

Another great kit module which you should equip is the Trajectory Bending kit, also from the Xindi & Infinity lockboxes. This kit causes spatial distortions near your targeted opponent, allowing your weapon attacks to always strike them from vulnerable directions. While this effect is active, all of your weapon attacks will Flank, and any critical hits you land will have increased damage.
An alternative for Trajectory Bending would be the Suppressing Fire kit which is available from the Fleet Research Lab. While this kit doesn't enhance your weapons, using your weapons will debuff your target. Another alternative would be the Command kit Hammer & Anvil which increases damage resistance for the team if the enemy is facing them, if the enemy is facing away from them it will increase their flanking damage.

The last kit you should equip is the Chroniton Micro-Torpedo Spread kit from the Temporal Defence reputation. This launches a spread of Chroniton Micro-Torpedos. The torpedos home in on your target and up to six additional foes within a cone dealing Kinetic damage, slowing, and knocking back their targets.
An alternative would be the Micro-Torpedo Launcher kit from the Terran Task Force reputation. This launches a Micro Photon Torpedo at your target. The torpedo homes in on the target, dealing kinetic damage on impact. The torpedo then explodes, dealing kinetic damage to targets in the nearby area and knocking them down.
Both torpedo kits are very similar and are quite effective.

Other Useful Kit Modules

There are many useful kit modules you can use, such as the Solar Gateway or Mass Gravimetric Detonation. If you want more information about what kit modules are available for each class/profession and how to get hold of them, please check the wiki.

Duty Officers

There are a large number of duty officers that you can use with abilities such as Ground Operational Asset cooldown reduction or Chance to beam in an additional Phaser, Disruptor or Plasma Turret, etc that will increase your effectiveness in ground combat. The Star Trek Online Wiki has a lot of information about what duty officers are available and also lists special duty officers and lists where to get them.

Colony Invasion & Other Special Ground Events

When you know you will definitely be going into a ground TFO/PvE, it would be beneficial to you and your team if you change all your active reputation traits to ground specific ones and also make sure you use specialisations that work on ground.

The recommendations as shown above have been tested by our admirals in the colony and by running elite ground TFOs/PvEs.

Note: This information does not include special fleet items.

Here you will find advice on the weapons and equipment you should be using to build your ship which will give you the DPS you need to do decent damage and increase your defence so you last longer in space battles. This list will not include special fleet items, only items available whilst levelling up, completing missions and some items found on the exchange.

If you are going to upgrade the gear yourself use the purple prototype tech upgrades, if you have any, because they don't need any dilithium and have a greater chance to increase the rarity of the item you're upgrading. These can be found in some lock boxes but are more common in the Dominion and Kelvin lock boxes (it is possible tech upgrades in lockboxes will be phased out now R&D is out on console).
Also, concentrate on upgrading all your gear to Mark XV before looking at increasing the rarity. Nothing should be a problem for you in PvE with Mark XV gear.
Once all your gear is at Mark XV you then can look at upgrading the rarity of all your gear to Ultra Rare, and then start upgrading the rarity to Elite.

The order in which you should upgrade your gear is as follows;

1. Shields
2. Deflector
3. Impulse
4. Warp Drive
5. All consoles
6. All weapons

General Information

Power on your ship is split between Weapons, Shields, Engines and Auxiliary.
At 50 weapon power you will be doing 100% of your base DPS. At 100 weapon power you will be doing 200% of your base DPS. At 150 weapon power you will be doing 300% of your base DPS.
Soft cap is set at 125 however this can be broken by using certain warp/singularity cores.
Your shield, engine and auxiliary works on the same formula.
You should ensure you keep your power distribution set to weapons as much as you can.

The weapon modifiers you should be looking for are [CrtD], [CrtD]x2, etc to do extra critical damage. Especially useful with using Overload which does an automatic 100% critical hit. Although if you're tactical, [Dmg]x4 is a better option depending on your base critical severity.
Accuracy can be buffed by another means.

For most builds you should be using a one torpedo, all beam build. If you favour cannons, that's ok, however they can be a lot less affective on some ships because of their limited DPS arc but can be devastating on other ships with the right setup, especially in PvP. Torpedo builds work really well when combined with science. When attacking using beams you should broadside enemies in a spiral or serpentine manoeuvre, keeping both forward and rear facing weapons trained on your target for maximum DPS.

If you are going up against an Intel Dreadnaught in PvP you will need to change your tactics. The Intel dreadnaught has five forward weapons and three aft. To take advantage of this you will need to get behind the dreadnaught and broadside from behind. Using abilities such as Evasive Manoeuvres will help stay behind slow moving ships like this. There are also traits to improve flanking damage.

This torpedo is an optional reward from Future Proof - Sunrise.

Torpedo launchers fire projectiles that deal heavy kinetic damage. Shields drastically reduce the effects of kinetic damage. In addition to the standard payload of a Quantum torpedo, Quantum Phase Torpedoes destabilize the quantum state of nearby shield arrays on impact. This quantum destabilization damages the shields of nearby ships.
High-yield Quantum Phase Torpedoes further raise the quantum destabilization, both damaging enemies and restoring allied shields within range. Torpedo: Spread causes the Quantum Phase Torpedo to trigger a single larger, more powerful shield drain centered on the primary target.

The Console - Universal - Mining Drill Laser can be obtained by the players of all three factions.

Romulan only - Kelvin Timeline T'laru Intel Carrier Warbird (Kelvin Lock Box, RRF Tier 6)
Federation only - [Console Pack - Proton Charge Launcher / Mining Drill Laser (Federation)]
Klingon only - [Console Pack - Auxiliary Ejector Assembly / Mining Drill Laser (Klingon)]

*Also purchasable from the Exchange for approx. 250k EC.

Although the technology was developed for civilian mining operations, a Mining Drill Laser comes standard on every T’laru. Easily weaponized, and potentially devastating, this long-duration energy discharge grows more and more powerful the longer you keep it focused on an enemy, while steadily eroding their damage resistance. The recharge time on the Mining Drill Laser is also proportionate to the time spent locked onto a target, allowing you to use it for brief bursts of additional damage at regular intervals if desired.
This console also provides a passive bonus to Max Shield Capacity and Shield Power Levels. (Note: Sources of max power do not stack – only the strongest applies, per subsystem.)

The Console - Universal - Proton Charge Launcher can be obtained by the players of all three factions.

Federation only - [Console Pack - Proton Charge Launcher / Mining Drill Laser (Federation)]
Romulan only - [Console Pack - Auxiliary Ejector Assembly / Proton Charge Launcher (Romulan)]
Klingon only - Kelvin Timeline D4x Pilot Bird-of-Prey (Kelvin Lock Box, KDF Tier 6)

*Also purchasable from the Exchange for approx. 250k EC.

With a focus on ambushing and overpowering foes with the maximum amount of available firepower, this Klingon Raider comes stocked with Proton Charge Launcher which can unleash a barrage of high-powered projectiles at both a primary target, and randomly selected secondary target, every half-second for several seconds.
This console also provides a passive bonus to the Maximum Hull and Engine Power Levels. (Note: Sources of max power do not stack – only the strongest applies, per subsystem.)

Spread improves your next torpedo attack. Launches multiple projectiles in a spread pattern that damage all targets in a large area around the target.

Torpedo: Spread upgrades the next torpedo attack to acquire N number of targets available within the firing arc, and fire N-1 number of that specific torpedo type per target. Example:
Rank 1 - Up to THREE targets acquired in firing arc, with TWO torpedoes for each target.
Rank 2 - Up to FOUR targets acquired in firing arc, with THREE torpedoes for each target.
Rank 3 - Up to FIVE targets acquired in firing arc, with FOUR torpedoes for each target.

Single target

This ability hugely increases the damage caused by your next beam attack from either a Beam Array, Dual Beam Bank and some Omni-Directional Beam Arrays; this attack will always critically hit. When activated, Beam Overload applies itself to all your beam weapons, however when the first weapon fires, it is cleared from all others, meaning that it may only be fired once per activation. The ability can be used effectively to quickly lower a shield facing, or to inflict significant burst damage to an exposed hull.

The ability's damage is a set multiple of the underlying weapon damage, with higher ranks providing a larger damage multiplier. Increasing your training in weapons skills will improve the underlying weapon damage, resulting in an increase in the damage of Beam Overload. Because of its higher base damage, a Dual Beam Bank will inflict a more damaging Beam Overload than a Beam Array.

With higher ranks of this ability, the proper tactical consoles, and significant weapons training, it is possible to inflict well over 30,000 points of damage to an exposed hull on a critical hit.

Having one Beam Overload buff active will prevent you from activating any other copies of Beam Overload. Consuming a Beam Overload buff to fire a beam overload will trigger a 5 second cooldown period during which no other Beam Overload powers can be activated. This 5 second cooldown period is not triggered if the buff just wears off due to duration/unuse, or if the buff is purged by a dispel effect.

Multiple targets

This ability applies to both Beam Arrays and Dual Beam Banks. A standard beam attack cycle is four attacks against a single target. After activation, all beam weapons will attack the selected target (if within its arc, otherwise a random target) and a second random target within their firing arc and attack them five times each (for a total of 10 beam attacks per cycle). The effect will apply to any firing cycle that begins during the ability's duration.

If only one target is present, only five attacks are performed. This ability is effective in delivering sustained fire against a few ships or for taking out fighter swarms and targetable projectiles.

Science Team is an ability that is usable in almost any situation in which a player may find themselves; it recovers shield strength and removes science debuffs. It can also be used as a counter to many debilitating science debuffs such as Subnucleonic Beam and is usable on yourself or an ally at a distance of up to 10 kilometers. Due to this fact, it provides a very effective cleanse and instant heal. It is highly recommended that all players have at least Rank I of this ability. Note however that even though Viral Matrix is a science debuff, its effect of disabling subsystems is countered by Engineering Team instead.
