See 2Tone's reply.
I'd like to add:
There is an incredible amount of luck involved in (big) multitable tournaments. Luck in getting good cards, luck in winning the coin-flip situations, and luck in stupid shit like... having pocket aces, not raising enough, getting called by 77, and there's a 7 on the flop. [You have no idea you're betting into a set, and he hammers you on the river.]
Other than that, don't worry about blind stealing until the tournament tightens up. At that point you can take advantage blindstealing - this alone will keep you going until you come upon a good hand.
There's not much else I can tell you without charging.
You wanna play tight, REAL tight. Don't make any unnecessary moves.
Keep in mind one more thing: this is a cheap tournament ... people will gamble w/ crap. Take them down w/ premium cards.
G'luck.
