You'll have a folder located at:
[your home folder]/music/itunes
This folder contains all of your music, along with the catalogue files, and I'm pretty sure that all you need to do is copy this over to your 'music' folder on the new machine. If my memory serves me correctly, I copied the files over using an ethernet connection when I set up my new machine, and it was pretty painless.
