I like the advice below about having two levels of priority max. One of the problems I've had getting into GTD is not having priorities. My stuff and actions are better organized, but I still end up not focusing on what I should. I haven't followed the thread, but I'd add the following.
1) Allow those priorities to change on a daily/weekly level as your "incentive structure" (e.g., boss's instructions or deadlines) change.
2) Make sure they match with whatever long-term goals you have. For me that's academic publishing.
