Never mind the bull****, just get a pair of good quality sunglasses, you really WILL need them. After that the most important things you'll need will be determination and diligence to get you through the low days when it will seem you can't do anything right (the first of these will be trying to hover in spaces smaller than a football field) and a hefty bank balance to see you throught the full course.
Most of all, relax and enjoy it!
PS - I don't propose to come between Whirls and NigelH so you'll need to decide as you go if bras and other recommendations offer any practical advantage!
