1. We don't know.
2. If I'm understanding it correctly, yes this Hank has the soul of the original. But so does bad-Beast. No, I don't get it either.
3. It matters to me and some others.
4. Plothole. I don't know why Hank needed glasses in the first place. Doesn't his healing factor cover things like that?

6. Probably not, but we don't know for sure.

8. We don't know. Seeing Logan oppose bringing him back hurt, as they were once good friends (even if he's rightfully suspicious).
9. We don't know.
10. Yes, but it seems to be glossed over.
