I lead the flop with a pot-sized bet, and two people re-raise behind me. Should I assume at least one of them has me beat, and fold?

[Insty]

Yes.
I'd probably bet less on the flop too, bet 170 or so. It's still a big enough bet to discourage all but the most enthusiastic of drawers, and save yourself some chips when you have to fold.

P.S.
This post would have been better if you'd left off everything after the flop action.
