Why don't you just copy the files back from your PC where you backed them up?
What? You didn't do that?
There isn't a magical 'list' of files, everyone uses different apps on their SD cards to achieve different things. So, work out what you want to use and then locate and download those apps. Wiibrew would be the place you need for non backup apps. Pretty much every other app will be available on Wiihacks but you need to know what you want first.
