Well as I understand it, you can authorize 5 computers. So it shouldn't ask you for password if you play the purchased songs on your pb, it would automatically authorize it, unless you already have 5 computers. Although I can't test this theory.
Okay: here's how you do it:
Power down your desktop.
Connect your new PB to the desktop with a FireWire Cable. Your desktop must have built-n FW and be running OS X.
Power up your desktop, and immediately press and hold the T key until you see a FW symbol on the screen.
You will see the name of you your start-up hard drive on your PB.
Now, make sure iTunes is NOT running. Navigate your desktop's HD until you find your iTunes folder. Copy the iTunes Music folder (the one containing all the folders with artist names) and then navigate to your PB's music folder, find the iTunes folder and paste it. It will ask you if you want to replace the current file with the new one. Click yes. Now, go back to your desktop's HD, navigate to the same folder you just copied from, and copy the iTunes music library file and paste it to the folder you just paseted to in your PB. Next, copy the iTunes music Library XML file from your desktop HD and paste it to the PB iTunes folder. Again, click replace when it asks you if you want to replace currrent files on the last two paste jobs.
You can now eject your desktop's volume from your PB. Make sure you are connected to the internet.
Launch iTunes. Before you do anything, go to the menubar, click advanced and authorize your PB.
You should now see all your music and all your playlists. Exactly as they appear on your desktop computer.
