There will be a few sites on the internet that have good general track day advice. Here are a couple to get you going.
Driving tips for track days
Track Day car preparation
For tyre pressure I suggest you start with standard settings and adjust on the day with a cigarette lighter compressor and a digital guage. You will then establish a pressure setting that suits ytour driving style.
I would emphasise the need for a decent brake set up. If you've got OEM brake pads on and have had them for any length of time you may want to consider getting them replaced ahead of the track day. Something like EBC Green stuff will provide a good compromise between general road use and occasional track use.
If you plan to do more track days than consider upgrading your brakes first (e.g. high boil point brake fluid, uprated front disks braided brake lines) before any other performance enhancements .
