No, you're not crazy at all for wanting to do that.
This would be my checklist for a first timer...
- Change brake fluid and clutch fluid to a high temp one (Motul 660, Brembo LCF, Brembo HTC 64 are some good options)
- Make sure tires have some life left in them
- Upgrading brake pads would be great but for your first time, you should be fine with OEM sport pads and rotors as long as they are still in good shape
- Buy a helmet after you figure out that this is something you're going to want to do long term. You can get by with a rental or borrow one from a friend in the mean time.
- Bring a tire pressure gauge, you're going to want to keep an eye on those throughout the day
