Has the tps ever been removed before? If not, it doesn't need adjustment. It should be 0.45v closed and 4.5v fully open. Search for "tps adjustment" on a few different forums and Im sure you'll find a good write up on it.

Pcv is just a check valve. air should pass through easily one way and not the other. Considering they only cost $3-10 depending on where you buy, just replace it anyway.

Are you talking about the holes inside the TB? If so, that means you fitv needs to be screwed back in. Search for this too. Its been covered over 100x.

Ah ok, misread your post. Yes try cleaning the IACV or replace with a known good one. Alot of aftermarket TB's don't have provisions for the FITV. Professional Products sells one for a gsr that does if your concerned about it.
