Hand 1: if this is where you thought you were too aggressive, I'd like to know where exactly you thought slowing down anywhere would be prudent. Your only other real option is to check/raise the PFR on the flop. But if enough players at the table are passive enough to call multiple bets at a time, then bet/3-bet is just as good if not better: you got nine bets in on this flop and check/raising probably would have only got you the same amount (assuming CO would have bet/folded to your c/r — I think this is a safe assumption since he's stupid enough to have raise/folded to your 3-bet getting 22-1 effective odds).

Hand 2: good limp. If you're at a table where six players are capable of seeing the flop, limping early with small pairs is good. Not your fault everyone decided to stay out of the pool this hand. Raise the flop.

Hand 3: thinly veiled brag post. You don't like JJ out of position; that's fine. But it's not like checking your option with it out of the BB will suddenly transport you to the button. You're OOP no matter what; raise both for value and the fact that it will clarify later decisions. If you raised preflop and the flop came something like Q84, you can safely bet/fold if someone raises behind you. Also, this was a good slowplay only in hindsight, since the only guy who had any threat at all was drawing to perfect-perfect. Actually, meh, this isn't bad to slowplay since it's so dry. But if the flop were JJ8 or JJ4 two-toned, go ahead and bet then.
