@atl77, you'll need
http://www.zezula.net/en/casc/main.html in order to get the contents of the new archive format used by WoW v6+, but I'm sure the data you need is not stored there. More than likely is is stored on the server and sent to the client only once the quest window is opened/accepted which will also explain why wowhead don't have it right away and need special software to get it.
@samyonair, how about you leave some work for the rest of us? You have a pull request with the updated Carbonite locales waiting.
