This has been mentioned, by why are you calling the flop?
Your flop bet is specifically designed to elicit a raise, so that you can 3bet, and hopefully have a capped flop. Most money in this hand must go in on the flop.
River action is unfortunate. Did you put the villain squarely on the lower set? This is the only reason I might've 3bet the river. But again, if you 3bet flop, you can get a better idea about the villains hand and the probability of him having a set would probably depend on whether or not he caps the flop. Also, a villain with stats like this would be raising the flop with draws a lot, so just calling the flop does not generate much extra action later.
