Just change the oil and add fresh gas of course. Maybe some injector cleaner. Go for a shakedown run to test the brakes. You'll probably have some brake noise but drive it anyway. You need to scrub the rust off the rotors. If the brake noise doesn't go away after a few miles you need to look into replacement.
