Cap it both times against un-nit opponents. Against tight players cap turn and as little bets on river as possible.

By the way why did you check-raise the turn? Problem if the opponents is a thinking one he will know immidietly you have a very good hand after your check-raise, and because of that you shoulden't actually cap both streets.
You have to keep open betting so your opponent has a bigger chance to missread you.(Over pair most likely)

Yeah, you need a read. Against a donkey who will overplay 3 8's that bad I might. Against typical opponnets after a raise on the river lead I would just call.
Also yeah, you want to donk the turn (I would pause for a sec too)--this signifies more weakness and give you a better chance to 3-bet.

Looks good. I agree with betting the turn so you can get in 3-bets there without giving away your hand to observant opponents.

Check-raise the river and call a 3bet, or just bet/call, read dependent. Getting it capped on the river should make you throw up in your mouth a little.
