tptk becomes 2pair but meets resistance. 3-6 (6max)

Alright. The table was playing fairly loose. The villan was a TAG and had shown down good hands at the river but was aggressive when involved. Does anyone disagree with the flop 3 bet?
When he caps I know Im behind and plan to fold the turn unimproved but then I do improve to two pair. Trips are unlikely he would have raised with any of these possible pocket pairs. 10 8 and k 10 I flopped the straight. How should I proceed from the turn onwards. Should I call down fearing the straight or raise and fold to a reraise or should I raise and call down if reraised.

Raise, and if 3bet call down. Looks like KT I know, but TAG could have QJ, QT, JT, T9 just as much I think with the UTG limp.
