Poker: Two Plays for discussion

[foghorn]

1. I'm in a tournament with about 1300 others. It's early, blinds are 15/30, and I've won a couple of big hands, so I am in the top 100 with about 3000 chips.
I'm UTG+1 and get AQs.
I bet 3x and get a caller, then SB goes all-in which is 600 chips for him. I call and the other caller folds.
I get an ace on the flop, he has pocket 8's and gets an 8 on the river.
I still think I would do the same next time though. Thoughts?

2. The very next hand I get AJo UTG and bet 2x. UTG+1 calls, and the guy that just beat me calls, then BB bets 360 ( raises 330) which is half his stack. Here's my mistake I think. Thinking I didn't want anyone else in the draw, rather than call or just put him all-in, I go all-in myself, 2400. UTG+1 calls, 1 fold and BB calls. BB has 88 and UTG+1 has AK. No A,K,or J on the board, but an 8 on the river. I'm out. Ugh.
I'm thinking I should have just called the BB or maybe even folded, but that's easy now that I know the outcome. What's the correct move?

1. No problem. It's still very early and you can afford to lose 500.

2. Big problem. Don't raise 2x UTG with AJo. Early in the tournament just drop it in the muck. Given that you raised, this time you have to lay it down because it might cost you a lot more of your stack.
