sorry i did not see this until now.
no you don't need new studs. the studs are steel and not torque to yield. if it was your second or third rebuild i'd suggest otherwise but for now this is fine.
yes you need the STi headgasket set. another name for it would be the EJ255/257 engine code which is the 2.5 turbo engine. this gasket will not de-laminate and fail like the stock N/A gaskets. its basically a direct fit and does something like affect compression by 1% or something stupid and not worth worrying about. there is no prep, you don't need to coat them with a copper spray or anything. just throw it on and torque to spec.
you want subaru p/n 11044AA642. this is for a 2004-2007 STi / legacy GT / Fozzy XT
here's the easy button:

make sure when you take your P/S pump off you don't flip it over or you might introduce an air bubble into the line, and then you'll have to bleed the power steering rack to get the bubble out.
