I'll preface this post by saying I think I played these hands correctly, but want some feed back anyway. If you think I made a mistake, please fire away at me, my feelings won't be hurt. I'd rather you tell me I'm an idiot and I learn from it

Setting: 5-150 table at a casino (we can't technically call it NL at the casino here, the max bet is 150, but for all intents and purposes if both people are ok with going all in no one will stop them). I find the players to be a mix of pretty awful gamblers, and solid players.

First hand:

I'm 2 off the button with pocket 10's and a $300 stack. Chip stacks are as follows: BB ~$300, player directly to right ~$240, player to my left ~$450. 3 people limp in, player to my right raises to $30. The player has been pretty tight, and a pretty solid player. I put him at JJ-AA, with a small possibilty of AK-KQ. The table had been together for 3 hours, so I had decent reads on people. I call hoping to hit a set, or having an over pair (although I would have only made a small bet if it were an over pair). Action folds to the button who calls, and one of the blinds calls. Pot is 125 (minus the rake). Flop hits 3 10 K rainbow. BB opens at $40, which is called by the next player. I make it $100 to go. I'm called by the button. He is a solid player. BB folds and the guy to the right of me goes all in, making the pot about $450. I go all in (covering the guy to my right +$28, because I obviously have atleast 2nd best hand), even though I put the guy on KK, because I know the button hit a good chunk of the flop and will probably call (either 2 pair, lowest set or possibly on a straight draw). Button indeed calls, making the pot about $700-800.

As it turns out, the guy to my right was holding KK, and button was holding AK. The board pairs on the turn and river, and I lose.

However, given the size of the pot, do you think I made a good call with 2nd best set? The first to go all in could have very well had AK, AA, giving me a hand I easily dominate. He could have been semi-bluffing, but given the size of the pot, I doubted that. So I figured I could beat 2/3 of his likely hands, and catch the 1 outter a minute fraction of the time. When I'm putting in ~$150 to win a 550 dollar pot with that kind of read I am getting the best of it correct?

2nd hand that busted me:
After rebuying in for $200, and then getting my stack up to $350, I get 77 in middle position. The button has been extremely aggressive and has me covered. He was frequently putting in pot size bets if the action was checked to him. 2 people limp in, I raise to $25, the guy 2 off the button called, and the button called. Flop comes 3 4 7 rainbow. I check, and action is checked to the button who puts in a ~$75 bet, as I expected. I reraise him to $150. Fold to the button, who thinks about it. I definitely did not put him on the straight, because he probably would have tried to get more money into the pot as the hand progressed instead of shoving in a pot sized bet. I figured the guy to either have flopped a set, had an over pair, or AK-K10.

He eventually calls. Turn comes a K, he shoves, and I call. He turns over KK and I do not hit the 1 outter on the river. Should I have reraised him all in (or atleast to 225 instead of 150, if they would not allow me past the "150 bet limit") on the flop? To be honest, I doubt it would have pushed him off the hand, but it might have.

Anyway am I wrong to think that if both these situations occured 100 times, I would make alot of money off them? Could I have played the 2nd hand better? Any other comments?
