1) Should I play this faster? Should I go pot/pot/push?

[/ QUOTE ] Ya, I think you should've been able to get it all in on the river and not have it be an overbet. Something like 25 on the flop, around the pot on turn, push on river. The push on the river would be around 110 into a pot of 197 with this line.
As played, I don't think you can get any decent player to call a push on the river. It would be really obvious his hand is beat. Betting 140 into around 130.
Given your read on his range, I think it makes alot of sense to play this much faster.
