I would install track or higher performance street pads and rebleed with motul 600 or castrol crf before you show up at the track.

Make sure fluids are topped off.

A good quality tire pressure gauge.

Empty out your car.. of everything. Even floor mats.

Purchase track event insurance. (Google: Lockton Motorsports insurance)

Hopefully, you have a good instructor. Have an open mind and receptive to suggestions. Leave your ego at home. You will get passed...by better drivers in miatas and E30s.

Consumables (pads, rotors, tires) will depend on pre-track condition, and how hard you are on them. A simple inspection for wear should suffice afterwards. I am anal about it, but I would change engine oil after a hard track weekend.
