FWIW, learning git isn't too critical, as long as you archive your directory before adding new features and bump the version (hey, its The Git Parable (how git works, inventing git ))
you can turn zip-files into a git repo when/if there is a demand ( if gitpan can do it :)
But if you do want to learn it I recommend http://githowto.com/ (Git HowTo TOC in spoiler)
