In general, if you are going top be runing track events like this, brakes are imp[ortant to take care of. Shoould use brake fluid like Motul RBF 600, braided lines if possible, and some good pads that can handle the track. My Hawk HP+ pads do work and are good for the street, but they fade after a bit in each session. I am going to step up to a Pagid track pad which can supposedly also be used on the street, but I dont think I will bother. As for the rotors, my fronts shos a little wear, but not bad, backs are fine.

Tires depends on how fast you drive, your alignment, and type of tires. I use Nitto NT01 r compounds which saw their 5th track day along with about 2500 street miles, and should still have a few more track days left.
