if you got heather mist, don't get the blue tint. if anything, stick with the black tint but bronze would look like nice too.
stripping tint off side windows is really easy...use a razor to pick up a corner, start peeling till all the material is off the glass, spray it down with ammonia window cleaner and scrape off the leftover adhesive using the same razor. as for the rear windshield, you basically do the same (peel) but you can't use a razor on the defroster lines. you might have to use a towel or non-scratching dish sponge (those green thingies made of plastic/nylon) and scurb lightly. the tint people would probably use a special spray but they still use something rough to scrub and most times, they don't guarantee that all the lines will still work.
