With most new iPods (I know at least the video iPods and newer) when you plug the iPod in to your computer it is recognized as an external hard drive. You can then open that, check "show hidden files" and open the iPod Control folder. In there is all of the data that is on the iPod; pictures, music, movies, etc... Copy those folders into a new folder on your hard drive and once that's done "un-hide" those folders and then add the main folder to the iTunes library index. I just did it with my old video iPod and iPod Touch when I got my iPhone because I was stupid and formatted my hard drive with my music library on it.Once you do that, it should start indexing those files. If you go in to the folder directly it will still have the gibberish titles, but the "ID3" or file name tag is intact so that iTunes will read the name of the song when it imports it into iTunes. I did have about 20 out of almost 2000 songs still read the four letter code in iTunes, but that's quickly fixed. The key thing is to un-hide the folders once they are copied, if you don't do that, iTunes will not find the folders, or more importantly the files in those folders.
