1) So you're saying that someone else raised and you must call that raise, correct? Here, I think it's ok to call a bet b/c your pot odds are pretty good if you flop a straight draw(which what you're really hoping for) or a flush draw(not so much b/c of your low cards--but that's just me). You're already in the hand for one bet anyway so an extra bet isn't all that bad. However, I think it would be ok to fold if you're not comfortable playing the hand.

2) AQ is a big hand, however it shrinks up a bit against a raise. Against TT JJ and AJ you're pretty much 50/50. Against QQ-AA and AK though you're an underdog who needs a lot of help. Because of this, you kind of want to play it safe and just call rather than re-raise b/c if you do then you might face an aditional raise(or cap) which shrinks your hand up even further. So bascially you just want to play it safe b/c you don't know what the raiser has.

That's my view anwyay.
