I am curious to know if the pcm must be reprogrammed(taken to the dealer)or is it just the same procedure as if it had lost battery power.

For what? Engine replacement? Then no, it does not require PCM reprogramming.

He has a couple or more threads running on the same engine replacement - hard to keep track.

Same car, same type/year engine, same PCM: put it all back together, do your pre-startup checks and drive it.

Normally I keep my posts together but this time it was a little different. I just wanted to make sure if it had to be reprogrammed or anything. Just don't want anything to get damaged.

Yeah, it won't require any adjustments. Erased settings and different values will be automatically learned by PCM while you are driving, given that you put a correct VIN matching engine.
