I know my post-flop line is wrong, but what's right?

[DrunkIrish05]

I feel like hands like this are the biggest leak in my game. Long-call type situations where I lost control of the hand. Also, this table was playing very fast with lots of big action on marginal hands. However, I had no direct read on main villain. Any suggestions on the hand would be greatly appreciated.
