I have a PSA AR-15 i am in the process of changing the barrel to a 20". I have the barrel, handguard, and gas tube w. pin picked out. My question is will i need specific armorer tools to make this swap successfully? And if so which ones to be exact?

Armorer's wrench
Upper receiver action block
Moly grease

A torque wrench that can set between 20-80 ft/lb torque also very useful for re-tightening the barrel nut.

Also a hammer/pin to knock out the taper pins on the A2 FSB (which can be a royal pain to get out); a Brownell's gas block action block is of great help to most people.
