I Limp UTG with AJs, same thing with KQs (or maybe fold), I would raise AQo.

If i'm raised after I limp, I call a min-raise or 2 more BB (as if I would have raised).

I think a CB would have been better because a) they could fold, b) if they call, you have 9 to 13 outs and they don't put you on the FD.

I would call the 150, not raise to 1500 (at that point you have to call the all-in). What a bad play by both players... min-bet with a set against 2 players and a FD on the board....
