Mike,
I wrote a mini tutorial here
WWW Link which may help you find the files you need.
I have done the clean install more times than I care to remember, and would suggest that you simply save the skin/theme folders to either an external disk, or to CD/DVD. This will allow you to do your clean install of the OS, hardware drivers, and programs normally.
Once Object Desktop is installed, you can simply copy the saved files to the proper sub-directory (folder) in the various Object Desktop program's folder and your done.
