One of the first hands at the table, so no reads on villains

Preflop: Hero is BB with K[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/spade.gif[/img].
<font color="#666666">1 fold</font>, UTG+1 calls, <font color="#CC3333">UTG+2 raises</font>, <font color="#666666">2 folds</font>, MP3 calls, <font color="#666666">3 folds</font>, Hero calls, UTG+1 calls.

Flop: (8.40 SB) K[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/club.gif[/img], 7[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(4 players)</font>
Hero checks, UTG+1 checks, <font color="#CC3333">UTG+2 bets</font>, MP3 calls, <font color="#CC3333">Hero raises</font>, UTG+1 calls, <font color="#CC3333">UTG+2 3-bets</font>, MP3 folds, <font color="#CC3333">Hero caps</font>, UTG+1 calls, UTG+2 calls.

Here I assume I'm ahead and go for a c/r. I cap this because UTG+2 could easily 3-bet the flop with TPTK or overpair.

Turn: (10.70 BB) 5[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets</font>, <font color="#CC3333">UTG+1 raises</font> a half BB and is all-in , <font color="#CC3333">UTG+2 raises</font> to the other half, Hero ?.

UTG+2 still raising worries me. I think he could have a set but TPTK or overpair are still possible so I think I should call down.
Is it right to call this down or should I consider 3-betting the turn?
