I changed to a newer lighter flywheel. I have replaced the rear main seal only 3k ago, and it doesn't leak. Can I accurately set end play with seal in?

Yes I am a little lazy, but these can be a pain to install w/o leaks imho.
IMHO if you don't do it, and it leaks you will have to pull it all apart right after
you pull your own foot out of your butt. They are not that hard to change
and not very expensive. But that is me.
