QQ vs min-limp/reraise

Sorry, if this is a dumb question, but i hate those spots

Party 33$ reg. blinds 200/400

65 people left, 40 paid, average ~11k
me ~8.5k


UTG+2 limps w/ 11k ( 30/9./1,0) only 40 hands
MP1 limps

I raise in MP3 QQ to 2k, UTG reraises to 4.6k...Hero??
well this represents obv Aces, but i often see people doing this w/ crap or AK at this limits...so what to do?
