Git Bash Completion
This is really an absolute necessity and a huge productivity improvement. Basically you need the bash completion script from the source tarball and use your shell profile to include it whenever you open a shell. See the Auto-Completion section on this page:

GitX git GUI
GitX is an awesome FREE history viewer made for OS X. It is a better way to visualize your branch and commit history of your git repository. However, power users (aka "cool kids") will probably only use it for history viewing while they continue to use the terminal command line for checkouts, branching, staging, rebasing and committing.

Git Tower
For those of you who just get panic attacks at the thought of using the Terminal, there is a commercial app for that:
Git Tower
I use Tower (bought it), but only for committing and fixing merge conflicts. I think Tower misses quite a bit of the flagship feature of GIT: branches. You can't see a branch tree graphically, like you can with gitX or even the command line (git log -graph -color, IIRC). But it's cool for committing. For everything else I use command line.

Using git locally on a Subversion Working Copy
OK, so you are addicted to git, and now you have to work on a team project that is hosted in a remote subversion repository ... and it is making you depressed :-(. Well, you can use manage your local svn working copy using git and be happy again!
I recommend you just use the git+svn protocol.
