Evaluating doing a rear main seal job.

Have read through all the threads that come up in search. Given the labor involved seems like its worth doing the full rear main seal (077103171N) vs the Timken 716102 + 077103181H gasket, but i can definitely appreciate the tradeoff.

Am aware that there's a slight chance it's not the rear main seal but we're pretty sure it is.

Have a very very slight leak from the trans pan gasket which is an obvious given the trans has to come out.

If I go to that length, what else should I be prepared to do at the same time?

Here's the rundown of everything already done to the car (905341) if anyone wants more context:
