I noticed nothing said about recovering from a extreme nose high attitude and low airspeed by rapidly unloading and rolling the aircraft with full aileron/spoilers into a 45-60 degree angle of bank to get the nose to drop. That is the advice in the 737 FCTM.
Also, to clear the decks as it were, the flight director should be immediately switched off if encountering a gross unusual attitude. This action is to avoid unwanted distraction of FD needles blocking the view of the basic raw data as displayed by the ADI. FD use and subsequent addiction as espoused by many operators can be potentially deadly in extreme UA recoveries
