Decent draw...call or raise?

[Perseus]

Just started playing the party 10/20 and don't have a lot of data yet. In this case I had just sat down and in the orbit or two hadn't seen anything fishy out of these players, but couldn't remember anything they showed down either.

Preflop: Hero is BB with T[img]/images/graemlins/club.gif[/img], 9[img]/images/graemlins/heart.gif[/img].
<font color="#666666">1 fold</font>, UTG+1 calls, <font color="#666666">1 fold</font>, MP2 calls, <font color="#666666">1 fold</font>, SB completes, Hero checks.

Flop: (4 SB) 7[img]/images/graemlins/diamond.gif[/img], 8[img]/images/graemlins/club.gif[/img], 5[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(5 players)</font>
<font color="#CC3333">SB bets</font>, Hero ...

With two behind am I better off calling my draw/overs or raising to maybe clean up some overs/free card the turn?

FWIW, I just called flop and turn.
