I created a clone partition of my main drive with SuperDuper on an external (USB) drive. How can I boot from it?

Press and hold the 'Option' key when you first start your Mac, which should then show you a list of bootable drives. You should then be able to select your external drive and go.

In addition to Brad's answer, before you shut down you can connect the external disk, open the "Startup Disk" system preference item, and pick the startup image that you want.
