what kind of gear am I looking for also
Tactical single fire Shotgun - that is a Shotgun of the Vagabond, Rebel, or Vindicator variety with forward grip. Vindicator works better with 20p ammo. Vagabond is suitable for with 6p and 3 p ammo. Rebel is somewhat if a jack of all in between.
I think it will be quite easy for you to take Concentrated Fire later on in the game, in which case you might want a Rapid 8.6 Muzzled Hornet with W2C bullets as a backup weapon. That is an Assault Rifle with 8.6 barrel, Hornet base, Rapid Reloader and + 2 Burst Muzzle.
Some form of High Frequency Shield Emitter.
For the head slot you can go for Muffled Unipsi Headband - that will reduce the cost of your Psi, or Seeker Goggles for ranged weapon + Crit. Having both and seeing which ones you prefer is best, but I think reducing the cost of Psi might be the better choice.
There are a lot of option for the body slot. Tactical Vest with Psi Beetle shell will give you some protection as well as boost Psi, but will also give some armour penalty as well, meaning it will reduce Stealth. Still possible to sneak around. Infused Rathound Leather Overcoat will boost your Crit chance and also give you very low armour penalty, so you might prefer that in the end - it will be easier to sneak with it. But that is not to say that you shouldn't pay attention to what enemies you will be facing. Sometimes having the right type of armour alone trivializes the encounter.
For boots I think it's best to have Ninja Tabies for extra MP and Stealth.
As for the quick items slot - you will see a lot of things to use here so you better get acquainted. I'd recommend getting Gas 'nades and MK III frags as soon as possible.
