BONUS TIP #1: Have Your Cake, But Don't Always Eat It
You can also catalog songs in your iTunes library without adding them to the iTunes Music folder. So, for example, you can admire the depth of your 'NSync collection anytime, but only listen to it when you mount the hard drive containing your boy-band library. To set this up, open iTunes > Preferences > Advanced and uncheck the box labeled "Copy files to iTunes Music folder when adding to library." Now you can store the song files anywhere, such as a USB flash drive, an iPod (if you've enabled Disk Use in iTunes' iPod Summary window), or another external drive. Whenever you mount the drive on your Mac, iTunes will play the songs housed there transparently, but if you try playing a song on a drive that's not mounted, iTunes will throw an error and ask if you'd like to locate it.
Note that only one logged-in user can have iTunes open at a time, so quit iTunes before switching users. If you get errors about the disk being locked, select your boot drive, press Command-I (File > Get Info), and tweak the permissions so the volume is owned by the System and the Admin group has Read/Write access.

Now just add music, and it'll be added to your library list.
