Western Digital external and ps3 help

[School]

last night i hooked my external hard drive up to the playstation 3 and i must say i was so happy most of my files worked.. both porn and audio.. here is my question. The audio files that are on my external hard drive are my ipod back up files some have pictures and some have just letters as names and they are arranged in f00 f01 exc but on my ipod itself they are all correctly catagorized . My question is how do i get all then file names and pictures up correctly. I know denon makes a ipod dock for the receiver that i have but if i get that dock will audio sound great like it does off my external because i have a monster cable that i hook the ipod up to that goes to my receiver and it sounds horrible no bass responce and static. As with the porn 95 percent of it plays and its sound great but some divx files wont play any suggestions thanks.
Also what would happen if i hooked my ipod directly up to my playstation 3 via usb would that work?
