While you should definetly have InfoCenter regardless of any other installed mod you might also want to check out Sage's Quest Journal as it adds the HQ and Writ information right to the journal page. That way you don't need to open up a seperate window for this type of quest info. It also makes the journal vertical, which helps display the information better.
