Here is a link to the gtkpod arch package:
Your ipod should work with that.
I have used it on a shuffle in Lubuntu and it works fine.
However, I do not believe that you will be to use an itunes account with gtkpod.
If you are interested in setting up an itunes account and using itunes on linux, it may work in wine, but I don't personally have experience with that.
Hope this helps.
