more information needed?

Didn't get any replys in the SS section, so trying it here.

Some basic paramaters... Hero is in MP with opponent one seat to his right.
Opponent loves to talk, plays his rushes, blames dealers for not shuffling cards properly when he is losing, loudly proclaims that he will never raise AKs because it never hits for him.
On the previous hand he mucks K6o preflop, and would have hit a full boat. You needle him to play his rush, (cause thats what i like to do to dicks like him) and he limps in the next hand.
Hero now has AQo and raises, and there are four to the flop of 8 2 2 .
Checked to the hero who bets, fishy BB and aforementioned opponent call
Turn Blank. BB checks and looks ready to muck, opponent checks, hero bets, BB folds, opponent checkraises.

1. What additional information (if any) is needed to fold this hand here and now.
2. What additional information abouth the opponent would cause you to call this bet and call the river if an A or Q hits.
3. What additional information do you need to cause you to call this bet and call the river unimproved?
