Rotors, get oem blanks, one with a warranty wouldn't hurt. Powerstop trackday pads, cheap and work well overall. ate 200 fluid.
340tw Firestone indy500 are pretty great for what they are. I did a few track days on my GT with them and they wore so well, would recommend those for your first year on the stock wheels. Cheap too.
Camber also.
Keep it simple as cordel said. Get.on track with the above relatively cheap route and gain experience. From there you can figure things out after some events.
