No need to do that -- the up to date fetish mainchat works fine. Just turn the titlebar on for the window you want to type in to prevent it from 'hiding' the chat entry area behind the text.
As for the quest journal -- make absolutely sure you're using the 11.2 updated file for the active quest window. Then go into your journal and make sure you actually have some quests checked to follow in the active quest window.
