Two questions:
1) should I have repopped AQo in the SB in this situation?
2) call or raise in situation below?

Don't know if I'm too weak but I fold AQo a lot in the SB after a raise. Maybe raising is fine too.

I'd definitely raise this weak bet. Check/raising seems ok.
Make it around pot-size to go I guess - ~$10
