Getting short, flop top pair - crappy kicker... good time to push?

[NYCNative]

I was debating on either folding or making a move and pushing PF however I didn't know what to make of the button call (I assumed it meant a weakish hand) and I thought that I might be able to push a raggy flop if checked to me and still have enough chips to be a factor. Instead, I flopped top pair with a crappy kicker and I was bet into by the chip leader.

Flop: (t450) 7[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/diamond.gif[/img], 5[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">SB bets t450</font>, <font color="#CC3333">Hero raises to t1100</font>...

Given my chip stack and villains range was this a smart play? This was a $30+3.
