I'm going to be selling a bunch of 6700 stuff soon, just haven't gotten around to it. I've got everything you've listed. The joystick is a part of the housing, requires tearing pretty much the entire phone apart - but that isn't that hard. In the post linked below I stated that I won't be including any USB cables with the cradles, but since then I've realized that I have a couple more than I originally though, so I'll be able to include a USB cable for both and at least one charger.
