Hey Not sure about this hand

Villain runs 12/10 over 40.

1) pf 3-bet bet-size? By default i'll make it 3x the open in position (4x out of position).
2) Do I flat the flop? I suspect villain's call/shove range is QQ+,AQs,AQo on the flop, so I'm happy raising and getting it in here.
3) If he turns QQ over, so be it. But should I really be worried about 33 and 22?

QQ+,33-22 [equity: 44%]
QQ+,33-22,AQs,AQo [equity: 56%]

I can't get away from this hand can I? My line OK?
