As for the music, I believe this means that the 'rock BS' is completely removed from this edition and replaced with the 'digitally remastered' original Japanese score. It might be selectable, though. So yeah, the Japanese language will naturally play on the Japanese music, which hasn't been on DBZ DVD releases before, other than the movies.
I'm kinda hoping they'll at least have "Rock the Dragon" in the extras, but if not I'll always have the awesome 3D rendering of DBZ Budokai.
