Can't help on any of the parts, but the window can get bought separately - I had to have mine swapped out when I bought mine last year because of cheapass tint on the window from the previous owner. Would be much cheaper to get the entire hatch used with the window already attached, though, obviously.
Good luck! I do see all of these parts on the forums and ebay every so often, so you should be able to track the stuff down eventually. Might have to be flexible on color, though.
