Alec, as far as I know shorcut sets are not saved as part of a workspace, but they are saved in a folder alongside in the same directory.
I think the path information for Graphic Squirrel may be easier to understand in Replace Your Preferences. There is no "roaming data folder" in XP (though the path listed in the KB article is otherwise correct).
There's not much point in moving clipboard scrap, or the other items in the C:\Documents and Settings\[User Name]\Local Settings\Application Data\Adobe\InDesign\Version [#]\en_US\Caches folder other than the InDesign Saved Data file itself (and even that one is questionable) when moving to a new machine. The rest really aren't "preference" items and will get rebuilt when ID is launched.
