Go and have fun. You won't be sorry. Don't worry about the car, it has so much protection you can't hurt it. The computer won't let you make an expensive mistake. The first time is intimidating but once your on the track and doing well all the worry's evaporate. You have a maximum street performance car, use it. I did and now I live for the next track day. (I really did pass 2 Z06 Corvettes! And a Porsche turbo too! (I'm not the most courageous driver but apparently more than those 3) The Honda S-2000 is perhaps the best platform to modify for the track, and the miata next. Don't fret, the X-fire is No. 3.
