Great post! And speaking of "Pages," I use the desktop version on my iMac to create epubs for my iPad. Set your styles, giving your chapter headings a "chapter name" style and export your doc as an epub. Then drop it as a book in iTunes. You'll have a nice TOC based on your "chapter name" styles.
Apple even has a "best practices" template available. For more info search the desktop version of Pages "help" for "epub." Also see Pages under the Macintosh section in the forum wiki HERE
