I need pointers!!

I am going to the 1/4 strip here in albuquerque this Saturday. I have never raced in my life......well not at the strip. I need pointers. I think I got the basics as far as who to watch and what goes on. I have a 63 dart in street trim with radials.( 360/904, 225/60/15, 8 3/4 3.23 gears with posi) I will be driving around the water and from there I'm lost.:)
When I'm at the line I am going to just leave it in drive a few passes to get used to it. I noticed from my last visit to the track that the cars actually launch before the light is green? What's the best way to time it? Just hit the gas on the last amber? I believe I will have to feather the throttle since I will probably have traction issues. Alright let's have some pointers please.
