upgrade path

i have a 91 ls auto w/ 185k...it's possible that i'm getting a 2-12 g grant..umm i plan to swap out the tranny to a manual and upgrade the clutch...probly get a new engine...then a suspension but idk what type other stuff i should get and i kno i'm pretty much gonna go boost but i wanna redo internals or w/e and i'm not sure like what type of parts i should get i.e. pistons, rods, crank, etc... and prices w/ the parts would help too...any opinions would be great
