hand reading help-50pl flopped top 2, see where i am, im ahead, right?

[lifes3ps]

initial 2bet on the flop is to see where im at obv. i figure set will raise, combo draw might raise, his call looks like a bare flushdraw or small 2pr.

turns a complete brick i think, so i pot again.
whats my line on riv? hes got $10 left pot is 50, do i c/c any? it looked like a fd the whole way but ill begetting 6:1 on a call.
