My First MTT win --- Three key hands (Little long)

OK, so it was only the $11 Party 99 player max tourney, but it still feels pretty good. Anyway, I've been mainly lurking and what I have learned on here has truly helped me up to this point. Here are three key hands that I's like a different perspective on. And no, I can't get any converter to work either.

Hand #1
Down to about 20 top 10 pay average stack about T7,000. Villian was playing well, never showing down bad hands, but never trying to make much of a play on anyone either.

I just know Villian has a 7 and reluctently lay this down. I have no idea what the Button has. Should I just call the initial river bet, or was the raise ok?

Hand #2

I know this seems very weak tight, but I hate to run into someone trying to get tricky with an Ace, and with my current chip stack am willing to win a small pot. This seem ok?

Hand #3

This looked all the world like a flush draw to me, and the CO had been really lagging it up with his big stack, so there is a good chance he is calling either way. Am I far enough ahead to make this call, or do I fold hoping CO busts him?

Thanks for reading.
