Brake fluid and a full bleeding cant be stressed enough. I use Castrol SRF (very expensive). Here is a handy chart of wet boiling points.

Dont forget to bleed the clutch, so that stays functional in the heat it will see.
As mentioned, "street" pads will not survive the heat from the track.
When at the track also pay very close attention to your tires, and their pressures. If the tires are questionable, consider new ones, and dont be surprised if they are junk after, and need to be replaced again.
You will also want to "nut and bolt" the car before going, to be sure your suspension is all tight, and ready for the track.
All are the the minimums to make the day, safe, and fun!
