asterroc | iTunes/iPod restoration for Windows

Anyone have a recommended software to rebuild my iTunes library from my iPod? I'm running Win XP and 2nd Gen iPod. I'd transferred all the files over from the old iBook, but the file structure is a mess and there's all these files iTunes can't find, so I want to just wipe what I've got and redo from my pretty pretty iPod.

Goddamnit. Sometime in there I reformatted the iPod for Apple - it was originally Windows formatted, but worked on either. This means it does not work on Windows at all. Which means I cannot transfer its mp3 files onto the PC. However I can transfer them to the theoretical upcoming MacBook, then plug it into the PC and reformat for Windows, then plug it back into the MacBook to get all the files from it back onto the iPod (since Windows format works on Macs), and FINALLY plug it back into the PC to transfer the Windows-format-mp3's back onto the PC. Yay.
