Don't even use iTunes. It's a waste of money. Download Limewire (includes a little spyware but nothing that Spyware Doctor can't handle) or something like that from www.download.com
There are also other programs out there, and you can also download BitTorrent. As for your iPod goes, doesn't it transfer through usb 2.0, which i believe is about 480MBPS. But yeah. try some of things and that should help you out A LITTLE.
