The preflop 3-bet is a little shaky, but not bad. It's a good mix from time to time and lets your opponents know that stealing from you isn't easy.

The turn bet/3-bet is OK. Calling his raise might be better, but that's negotiable.

Folding trips anywhere on the river is not a good idea. Are you really that desparate to save a single big bet in a 13+ BB pot? Even if he resteals < 10% of the time it's worth a call. Not to mention you can easily have the best hand against a slow-played premium pair.
