nl10 - flopped straight; now what?

[pixz]

My main question is about what to do on the flop (lead out-slowplay-C/R) and how is my play on turn/river.

So i flopped a straight, and made a lil bet on the flop.
I get reraised and I thought about it for a sec but eventually just called, i didnt want to raise tp out of this pot.
The turn is a decent card i think and I went for the c/r.
The nine on the river sucked and because its a pretty good card to bluff i dont want to check to him so i made a blocking bet.

Sanity check? pls
