I would fold preflop. If you were deeper, say you had 10,000, I don't hate a call.

As played, on this flop, if he bets and you plan on doing anything except folding, you need to push the rest of your chips in.

A few notes on your observations:

Good TAGs open up as the tournament progresses. In later stages, their playing style might be completely different from the earlier levels. You do need to open up and be more aggressive near the bubble, but you need to pick your spots. Playing AXs with a small stack relative to the blinds against a raise isn't a good example of carefully selecting your spots. If it had been folded to you on the button, open raising would be very standard.
