Fold preflop. Your hand is a piece of crap, and once the button raises you definitely should fold for $1.25 more and having to play out of position the rest of the hand.

The river is a fold also. He probably doesn't have an A, though I suppose he could've had A5 or the NFD. I think he checks an A though, since you showed strength twice. I think he likely has a boat. You might think he would raise a flopped set on that board, but a lot of people get too cute with strong hands. I suppose 33 is also possible. But I don't think you're up against an A enough times to call.
