If you have a network setup in your house you could transfer the files that way. This is usually done wirelessly, but if you dont have a wireless connection and are just using a wired router this should still work fine. This link will show you everything you need to know to get your computers to share files, ive had luck with this and a lot of people on the forums have had luck with it as well so I know it works.
To add you can use a stright ethernet cable and connect the mac to pc. The port on Mac is autosensing and will make the crossover connection for you - that means you do not need a crossover cable or patch cable to do this, just a stright Cat5/e cable. You'll need to setup some shares and move them over the wire, which is what the fore mention info states.
You can use your iPod! I did it last week, took me about 30 minutes to transfer everything. Easy peasy, because I had to deete/restore my iPod to format it for the Mac anyway. And so long as you copy over your music folder and re-import, you won't have a problem.
