"stealth" package, what is it, what things it adds to the car?
That's just a black finish -- instead of silver -- on the rings around the exhaust tips and the airbrake mounts.
I wonder if you guys can list the options that you know of and what additions it gives to the car
The carbon-fiber pieces are exactly the same as the regular plastic pieces, just made from a different material; weight savings are minimal.
These are the options on my car; if you want to see photos of any of them, just ask. Prices for the options probably varied from year to year. The prices below are from my car's window sticker:
