Advice for beginner wanting get into drag racing?

Thinking about finally going to a track this summer. I have never raced in my life. In addition to safety concerns and mechanical issues, I guess in all honesty I also don't want to look stupid in front of people... Are these a good start in terms of reference? Or is there a drag racer bible so to speak of what everyone uses?

If you still own a VCR this is a really good video for Drag Racing beginners.

Good luck, be safe, and have fun.
