Forget about going fast. You are there to have fun, don't let you expectations over ET and MPH ruin the experience.
Just focus on making as many passes as possible...the rest you'll be able to figure out pretty easily once you get more comfortable. You will be nervous, and that will affect your "performance" more than optimizing launch RPM, tire pressures, or shift points.
I've made hundreds of passes down the drag strip, and I still mess up.....
