If this is your first track event focus entirely on safety items. Do not concern yourself with speed, focus on learning (from your instructor) how to safely operate your vehicle on a track. To prepare for following track events work on changing things that'll allow your car to deal with heat better (tires, brakes, etc).
For a first track day I think these things are critical:
1. inspect your brake lines, if your 2011 has the originals you may want to replace them with new OEM lines
2. flush brake fluid. Fresh OEM brake fluid will be sufficient.
3. check pads, if there's any question as to how much life they have get new ones.
4. inspect rotors for micro-fractures or any cracking, replace if necessary.
5. test drive, if rotors are "warped", as in there's pulsing through the peddle that is not ABS engagement, get the rotors turned (if within spec, I prefer brand new to turning) or replace them
6. inspect tires, replace as necessary.
I'm a huge fan of speed bleeders on the brakes. These will let you take a pump or two of fluid out of each caliper in between sessions as necessary or at the end of the day by yourself and with the wheels on.
Throughout the day perform a basic visual inspection after each session; oil, coolant, brake fluid, tire condition & air pressure. Have a close look at each sidewall and if you feel that the tire is rolling over too far, add air pressure. If you're running even a basic sport tire like a Bridgestone RE760 the sidewalls should be stiff enough that your "hot" pressures should be fun at somewhere under 40 PSI, but if you're running all seasons you may need to add more to keep it from rolling over.
