Looking for 99 in all the wrong places

[DaNoob]

Setting: 1 Table, $5.50 NL Holdem Tournament at PokerStars. Play is slightly more aggressive than I'm used to for the tourneys, but not outrageous, and people seem to have the cards (not bluffing). 1500 chips to start.

Game 1 (Mr. Hyde): 7 ppl left - 30/60 stakes. I've got ~2100 chips, which puts me in 2nd at the table, sitting MP. I get dealt 99. UTG calls, +1 folds, I limp in, next guy raises 180. He has been playing somewhat tight, so this gets my attention. Button folds, SB calls, everyone folds to me. I fold.

Did I play the pocket 9s too meekly?

Game 2 (Dr. Jekyll): It's about 20 hands later and we're now down to 6 players. My stack has slowly dwindled, as I've been dealt pretty crappy cards as far back as I can remember. I'm obviously itchin for some action (prob very foolish attitude). I'm in MP and get dealt pocket 9s again. This time, feeling more confident about them, especially after my previous experience. UTG calls $100, +1 folds, I raise All-In. It folds to BB, who calls, and then UTG calls also. After my meek performance on the 1st hand, did I overdo it on this one?

I'll share the results after some initial feedback. I don't want to skew any judgements.

Also, if I've left off important details, let me know and I'll fill in the blanks. Thanks!!
