How to prepare for tournament?

[colpres]

While passing thru Chicago 6 weeks ago, stopped in Harrah's, heard that seats available in $40 10 player satellite, won! So tomorrow I fly to Chicago to play in a Sunday 60 player NLHE tourny made up of all the other winners - 1st is WSOP entry & $3,000. Four other places pay - don't know what.

This is my 3rd live tourny - lost one in CA 6 months ago, and the satellite was number 2! Only played the game for 1 year - lots of $3 & $5 MTT and $5 & $10 Sit n Go's on-line, won 1 550+ player MTT in June for more than $850. I'm up about $50 (I know, big bucks) for the 14 months since my very first deposits - most of my losses came in micro-size ring play or not winning massive MTT tournaments in the first 3 - 6 months.

From all you veterans - what do I need to know before Sunday's starting gun? And then how do I decide on an appropriate strategy? If $1000 chips and $10-20 blinds, I'm pretty sure $2500 and $10-20 is different, so how do I decide on appropriate play? I'll try and study other players, hopefully not tilt, WILL NOT WEAR UNIBOMBER SWEATER, etc. As you probably know, I'll be excited and nervous. You help would be appreciated - maybe wish me luck as well!
