1. yea i agree he usually 3bets AQ and probably c/c's flop with Qx around half the time. plus your hand looks like Ax that hates this river. i'd call

2. c/f is standard

3. this spot is hard because you set it up for a roughly PSB shove on the river but then the flush draw completed. I can see the merits to c/f based on the runout and the passiveness of villain. even if we gaybet the riv for $65 he probably isn't calling Qx and there isn't a lot of Kx in his range, plus $65 is so transparent as fearful of the completed flush after the c/r + turn barrel.
