If you don't know the wiki I'd suggest you to take a visit!
I can recommend the following posts:
http://induktio.net/wiki/Colored_messages -> Look in the section Enable colored server names on the top of the scoreboard.
http://induktio.net/wiki/Useful_tools The toolkit seems pretty cool especially if you need a fresh install and don't want to change all the settings manually. EDIT: (This download link will work).
