git-tfs is a two-way bridge between TFS and git, similar to git-svn.
git tfs clone http://tfs:8080/tfs/DefaultCollection $/some_project
(wait for git-tfs to pull your history)
-or-
git tfs quick-clone http://tfs:8080/tfs/DefaultCollection $/some_project
(cd some_project and hack away, using only git, until you need to share with TFS...)
git tfs checkintool
-or-
git tfs checkin -m "Did stuff"
git tfs shelve A_SHELVESET_NAME
git tfs help
Download or build.
Add the directory that contains git-tfs.exe to your path.
I've been using this with msysgit 1.7.3.1 for a while.
You need .NET 4 and either the 2008 or 2010 version of Team Explorer installed.
msbuild (included in .NET 4) should be able to build the entire solution.
You can also do rake build:debug.
