Just replied to your PM.
Lots of good input from above. Since the car is NA and the drivers is new to the car, the most important prep is yourself, IMO. This is a lot different than the Mazada 3! The car has snap oversteer in a millisecond by comparison, so you should really tip-toe into the corners. Understanding how to throttle oversteer and trail brake a mid/rear engine like this car is the toughest part about learning how to drive the elise but it's also the key to keeping the car out of the wall if you feel you're coming in "too hot"...
As others said, flush your brake fluid and replace with ATE or similar. Make sure your pads are in good shape. Short of the basics like tire pressure, your next step is a simple, but detailed, a full inspection of fixings about the car. Key check points are the toe-links, wheels, and uprights.
RE the toelinks. Remove the nuts and pull the links out a bit to expose the studs. Inspect the studs for any wear or deformation. If they look good, then reinstall and tq to 45lbft. Inspect these fasteners before each track event. As you get faster and more fully utilize a r comp tire like the 048 or 888, it will be a great idea to replace the links with something from the aftermarket.
While you're getting started, the oil pan and fuel starve issues are not at the top of the list, IMO. They're important, but you're not going to be pushing things that hard for a little while. Be sure the fuel is topped off before you go out and enjoy yourself... Again, you'll want to upgrade these parts as you start pushing the car, but the first sevral sessions out will be like trying to learn to drive all over again compared to the Mazada 3...
Again, go slow. These little things are nothing like front engine 4 door with wrong wheel drive...
Call me any time.
