Make sure your brake fluid is flushed. As a noob, you shouldn't be too tough on brake pads, but boiling fluid is pretty common.
My buddy is also a noob, and is bringing his yellow 11K-mile '04 Mach 1. We flushed his fluid the other day. He was surprised at how dark the fluid near each caliper was. Other than one day at the strip a few weeks ago, the car has lived a pampered life. Over time, though, moisture still collects in the fluid.
Oh, and it looks to be warm out. You have to wear long pants & long-sleeve shirt while in the car, but no need to suffer while you aren't driving. I go in a t-shirt & shorts. Many of us have a pair of $10 Wal-Mart cotton pahama bottoms with the drawstring top. Buy a bigger size that you can pull up over your shoes & shorts.
Also, I used to bring a long-sleeve t-shirt and just change it before driving. BUT, if you are sweaty, that's a PITA. What I do now is bring an old cotton button-up dress shirt. Easy to put on/off when needed.
I also have a couple of Nomex flight suits that I bought for work off eBay. They worked great at the track (VIR) last year, and I bought a bigger size to fit over my t-shirt/shorts. Unfortunately, they are in my work trailer 500 miles away!!
Bring a folding chair for the track. Also, if you have a pop-up cabana, that's great for the sun.
I use an old tent tarp to put my stuff on that I pull out of the car. it is big enough to double-over the top of my stuff in case it sprinkles. or just to keep the sun off.
You will have to pull everything (mats, empty trunk & glovebox, etc) for the track. If you have unneccessary stuff in the car, just leave it home. less crap to deal with.
Torque wrench & proper lug socket to check your own wheel torque. As (obviously) a tire gauge. They have air at the track.
Small cooler with water/Gatorade/whatever is good.
Throw a few rags & a roll of paper towels into a plastic shopping bag. I also bring a package of Wet Wipes. Very useful.
Remember the Tech Form, although I & others bring spares.
Remember your helmet!! Put it in the car NOW!!
