With regard to git:

I have been playing with git and its a bit of a muddle as there are so
many options and alternatives which cover similar command
subsets. Having just discovered dvc the waters are even muddier.

But if you use emacs 23 then most basic revision control commands are
there are described in the version control section of the emacs manual.

My personal favorite is here as it includes a good tutorial but, for
some reason, refuses to status my .emacs.d.  But it works well with
org-mode project which you can clone. Note the use of the graphical tool
gitk too. It is also the only one which use ediff as a default and the
only one which provides graphical status bar indicators of your file's
git status.

The most promising one with regard to staging and branching is magit:

And the author is generally online in the #emacs irc channel.
