There is also "Think Like a Git" (http://think-like-a-git.net/), "The Git Cheatsheet" (http://ndpsoftware.com/git-cheatsheet.html) and "Git, the simple guide" (http://rogerdudler.github.com/git-guide/). This might just be piling on to your 'yet another tutorial' list but maybe one of these will help it click for you.
