I don't see anything to add to the policy on categories. Going through all images might take some time, but if more than a single person does it that wouldn't take as much time as checking all pages to apply the new policy.

Btw, you should add the link to uncategorized files to this post, so people willing to help can see what's left to take care of: Special:UncategorizedFiles.
