Get yourself a suitable brake pad and fresh fluid. Spend the rest of your money and time on attending more HPDEs -- maximize the use of any instruction they have available. Don't bother with all of the race car driving books yet, you need to focus on getting seat time and learning the basics.

I'd suggest budgeting this out because you WILL use up a lot of brakes and tires (so be sure to check their status often and know the warning signs for replacement, too). Entry fees add up as does the gas the car drinks during the day.
