1st time at track next Wednesday - need advice

I finally fixed my vibration and am heading to Brainerd International Raceway this Wednesday for Wednesday Night Drags. I have never raced on a track before. I need tips, advice, warnings ..... anything I can get. I am trying on some drag slicks that my brother has this weekend. They may or may not fit. They are 28 X 9 but are on wheels from a 67 Fish that he says has a weird offset. If they don't fit I am running my normal P295/50R15 BFG Radial TA's. I have a 408 stroker at 500hp, 200R4, Dana 60 with 4.10, Caltracs, Calvert Racing Adjustable rear shocks, 90/10 front shocks, and line locks.

I need all kinds of advice. Prep, launch, etc... HELP!
