Jeff - I can't tell you anymore than I know about mine. I have a hair over 80k on mine and I believe it's on the original clutch. It still seems to be holding up OK. Of course, it really depends on the driver and the regular usage. I doubt there is a 'normal'.
The RMS issue was, if I recall correctly, helped considerably by a new design of seal fairly early on. I don't remember the exact date or details but I doubt you will have any issues. Again, I'm happy with mine.
Extended warranty - no information at all I'm afraid.
2002 on the whole does not appear to be a problem year. You stand a good chance of having to deal with the regular issues before too long. Window regulators need replacing due to cable stretch, brake light switches wear out, headlight and ignition switches too. These seem to be normal wear and tear items and are relatively inexpensive and easy enough to do yourself. I've also had issues with the voltage regulator in the alternator. Again, relatively cheap and easy enough to fix. There is a growing number of articles on here and other sites that give very good DIY information.
I honestly think you would be pleasantly surprised.
