For empeg use you don't need any type of logical filenaming structure. You just need ID tags for it to pull information from for its database.

MP3Tag Studio will probably be your best bet for the renaming operation you want to do, as well as your initial tagging (if pulling the tags automatically from the filename). It is mroe robust than the other programs and has some excellent naming rules for case as well.

When you want to manipulate tracks based on anything other than directory structure, you will have to use Tag&Rename or Tag-It. MP3TS doesn't have support for anything other than recursive folder structure (or specific files within one single folder).
