For your brake fluid, I'd recommend looking at the fluid and making a judgement call. If the fluid is a clear light gold and you're not flogging your car hard at the track, I'd say leave it. If the fluid is turning darker, or if you're putting the brakes through hard use (at the track, for instance, or lots of hill driving), then go ahead and change it. Changing brake fluid is not rocket science, and a good brake bleeder system and a few quarts of Motul 600 brake fluid will be way cheaper than the dealership.
