yup... the general prep as far as body work goes is tape over all lights and remove brake light bulbs or pull the fuses.
I remove my mirrors and license plate as well.
In addition, I safety wire my oil filter with the help of a hose clamp. My oil drain plug is also drilled for wiring. Don't ruin people's day just cuz something worked it's way out and your bike spilled oil all over the place.
Here's the bike prep page on the local trackday website in my neck of the woods. The rules vary from track to track & organization to organization, but this page is pretty indicative of what the common rules are and will help you make sure your bike is track worthy.
