First,
Make sure you have at least 1 friend with you.
If this is your first trackday, i'd recommend removing ALL of your bodywork from your bike. buy some cheap race stuff that has been crashed if you can.
Street bodywork is expensive.
Go with a friend that has been out to a few trackdays and ask them to show you around, if that's not possible, ask the trackday organizers if there are any racers attending that would mind showing you around the track.
Most trackdays have this type of help available, if they don't, just watch the fast group and look for the more experienced riders in that group and introduce yourself to that person and ask for some guidance.
Maybe offer to buy them lunch if they spend 30min or so(2 sessions) working with you.
Also, if you're tired, don't feel like you HAVE to get out on the track. You make mistakes when you're tired which will lead to crashes.
Its your first trackday, do 2-3 sesssions and see how you feel, if you're tired, pack it in for the day.
paying $140 for the trackday and doing 30 laps is a much better investment then paying $140 for the trackday, trying to do 40 or 50 laps and driving home with $1000 damage to your bike.
