If they are both on wireless and connected at the same time, just open finder from the computer that has your tunes on it, click network, browse across to servers and see if you can find the one from the other, then connect to it then open the public drop box folder and drop all your stuff (folders, files, etc) into that folder. Then go to the other computer, open finder, click your username, find the public folder, and inside it will be the drop box that has all your stuff. Drag it all out to wherever you want it to go.
