I use Continental slicks, as Rick stated you will never run street tires again. I buy them off kijiji. Approx $75-100 each.

You should have dedicated track brakes. One experience of brake fade into a corner is all it takes.
I've personally only run Hawk pads for no reason really. Hawk HPS pads don't work in my experience.
Hawk HP+ front and rear is what I'm currently using. Work great, reasonably priced, but may not last as long as other pads.
Plain old Ford (brembo) rotors too. Just can't kill those rotors.
