Check out this site, put up by Dennis Curtin: ShortCourses.com
I’ve browsed through the site and found it to be a very good introduction to photography in general, with some nice insights about digital shooting in particular. Check out the section on work flow as an example. If you like what you see, you can purchase the book Dennis offers.
