A couple of ways.

You can checkout the branch, then forcibly reset both the branch
and your working directory to some other revision, like say
origin's master.  Note this will overwrite any modified but not
committed files!

  git checkout master
  git reset --hard origin/master

or delete the branch and recreate it:

  git branch -D master
  git branch --track master origin/master

or just delete the branch and don't even have a master:

  git branch -D master

Read git-tag's manpage.  Creating a tag is as easy as:

  git tag -a tagname

then you can later go back to that version with:

  git checkout tagname

if you have that version checked out you can find out what the
tag name was:

  git describe

you can also export that version as a tarball, even if you don't
have it checked out:

  git archive --format=tar tagname | gzip >tagname.tar.gz

Does that help any?  Tag names are treated almost like any other
revision identifier (commit SHA-1, branch name, etc.) in git.
