unless there was some sort of interlock with the reverser, I would think that after an engine was shut down all throttles would be moved as one (assymetric issues aside).
given a choice it is probably better to be too fast than too slow on an approach ( chicago midway aside!).
I would like to hear about fatigue issues, the last time this crew flew together as a crew, the previous aircraft that the crew had flown ( most AF reserve/ANG are airline pilots)
I recall a crash in which the pilot, flying a 737-400, said he confused the rudder "feel" with the C130 he had just flown in the guard.
Back in the old days, airline pilots got lots of time off...they rested and hopefully came to work read to fly...but with hard times at USAIrlines, topped off with miliatry duty, fatigue may have been part of this equation.
