The tappety sound is air in the oil. You need an apollo tank which lets the oil rest for a bit and the air floats out if it whilst it rests, ah, how nice!
You won't get brake fade unless you're a real hooligan.
Before you go check your pds have some meat on them and ensure your wheelnuts are at the correct torque. Do this after the day too. Take a pressure gauage and footpump with you and pump your tyres slightly harder then normal (say 22 psi on 185/60s).
Check your oil level is ok. Check you water level is ok. Check all your levels. Try super unleaded for extra safety if you feel cautious some engine builders recommend it for the track. get your wheelbearings checked before going on the track and get them adjusted if needed.
Take it a bit easy on your first outing. If it's fr, go B&B the night before - you'll be knackered at the end of the next day. Take a spare and go in convoy if possible.
