Canvas Page URL: This is the most confusing part, and wasted me heaps of time. What they want you to enter is basically a directory name for your applcaition. The name must be 7 characters or more, and must be unique from other Facebook applications. I used guessab (so you can’t). When you add http://apps.facebook.com/ to the front you have the Canvas page URL.

NOTE: If you use upper case in the Canvas Page URL, it will be converted to lower case automatically. Also, case is important, so if you use upper case in your links later on they don't work. http://gathadams.com/2007/06/18/how-to-write-a-facebook-application-in-10-minutes/
