During the preview stage just collect 20 to 25 trigger words/phrases (they don't have to be single words) for the section you are working on... don't worry about forming questions yet.
Form questions from the trigger words/phrases following photoreading and the quick post view... you'll probably find yourself asking better questions.
During activation (at least 20 minutes after photoreading) keep reminding yourself you can flip through the pages repeatedly (in effect your mind glances at this information a number of times). It might help drive away the urge to rapid read long sections too soon.
You might want to apply a time constraint on the rapid reading if you keep finding yourself falling into it too soon.
With mind mapping I understand what you mean. You could try out some other forms or note taking... like the herringbone technique. The Northern Territory Universtity site has some other techniques worth considering. I think mind maps prove to be the most annoying for people who work with auditory senses for learning so why not make a brief summery of your notes into a tape recorder? It has been shown that we remember 80% of what we say. Something like 70% of what we see and only 40% of what we hear. So just taking about what you learnt into a tape has the potential of being a great memory aid.
