QTs, flush draw, second pair

[Boolean]

First orbit at this table. I'm not sure exactly how to handle this type of hand. This was at a beginners table, so my opponents are rarely very good.

Preflop: Hero is UTG with T[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/spade.gif[/img].
Hero calls, <font color="#666666">1 fold</font>, MP1 calls, <font color="#666666">2 folds</font>, CO calls, <font color="#666666">1 fold</font>, SB completes, BB checks.

Okay limp?

Flop: (5 SB) 2[img]/images/graemlins/spade.gif[/img], 8[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(5 players)</font>
SB checks, BB checks, <font color="#CC3333">Hero bets</font>, MP1 calls, CO folds, SB folds, BB folds.

Great, a flush, so I bet here for value.

Turn: (3.50 BB) T[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets</font>, MP1 calls.

Here, I pair up. I can still make a flush, or two pair. I could be behind an ace here, though.

River: (5.50 BB) 4[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets</font>..

I miss, but I bet. I find it unlikely that most players will call this far without an ace. I'd fold to a raise. Is this an okay line, or should I check/call?
