First time at track. Advice?

I say it depends whether you drive it to the track with the slicks on or not.
Is it 20 miles or 300?
If there is ANY CHANCE of rain I wouldn't even consider it, since you can only do about 45 in the rain with slicks without the rear end constantly hydroplaning.
Been there and done that, and though it's kinda fun it's a pain trying to get somewhere.
