Just to help out. The crank spins on main bearings. The rod bearings onto the crank are big end bearings. AUM pistons are 19mm pins. Get the crank checked, balanced and polished if needed.
Dont go largeport. Will be worse than the smallport for that size of turbo. Better off getting the smallport polished. No need for arp headbolts/headstuds. Std ones are fine. Valves and springs are dependant on how much you want to spend. Go for Supertech valves and titanium springs and retainers. Looking around £800 though. Headport is £750 inc skim and fitting valves with new guides if needed.
Red lube is Torco engine assembly lube.
