PowerPC :: Transfer Projects Form G4 Laptop?

I have a G4 laptop with Airport and bluetooth, and have just bought a MacPro which needs to go back because it's faulty. Problem is, they say the bluetooth module is not available anymore for my replacement MacPro and I didnt order a airport either, Im not to fussed about the wireless keyboard + mouse but I was going to use bluetooth to transfer files and share the internet connection from the G4 when needed (The MacPro dosnt need constant connection, only for updating, registering etc). Now, getting the replacement macpro has already taken about 3 hours of phone calls so im not sure if its worth trying to get the bluetooth for what its worth, I dont know if this is even the best way to share files and connection? Would using the ethernet be easier, I assume I would still need a hub like with PCs? Is it possible to use a cheap 2-4 port hub or do I need an expensive mac one? Or should I press them for an airport?
