Maintenance prior to dropping everything back in the car

I'm buttoning up the odds and ends prior to attaching the trans to the engine and the engine to the k member and rolling the whole thing back under the car.

Any suggestions on maintenance prior to putting the bell housing on or the 4 speed?

I haven't even taken a thorough look at the rear of the engine yet.

Maybe something with the clutch? Mine looks fine but I have never looked at a clutch up close before.

Anything else to check out or keep and eye on or grease up?

I can provide pictures of stuff you suggest.
