How does this look? Should I have reraised the flop? The BB betting on the turn caught me off guard, hence I called down the rest of the way.

Yes, you should 3-bet the flop. Button might have caught 2 pair, but more likely he paired the A (or even the K or T) with a lower kicker than you, and is raising because he suspects QQ or JJ of you. I think you're still ahead often enough to justify the 3-bet, and if you are you certainly don't want to make it cheap for another Q or a J to stay in with thier gutshot draw.

BB likely either caught 2 pair or a set of threes on the turn (probably A3, if I had to guess). I agree with simply calling down after that.
