Top Two Pair Good?

The table was really passive/loose preflop, which is why I called with ATo UTG.

UTG+1 is 31/7 over 300 hands.
MP1 is 12/2 over 50 hands. He's fort knox. Tight and hasn't showed down a hand yet.

Hmm...top two pair good? Internally, I went something along the lines of..."Ah crap, one of them has a set. Especially the rock. Oh well, I'll call. There's too much money in there and I might win...I hope they caught A8..." Were my lines good?
