Sounds like on downshift the transmission has a delay, transmission "slips" out of gear.

My first step would be to change transmission fluid & filter if it has not been done recently. (Assume level of fluid is ok).

2002 Lincoln LSE 3.9L 124,000 MI. stalls after a stop or hard braking.

This may be a "sticky injector"

This would cause overfuelling - and a sudden rise in RPM. The ECU will see this and compensate - by shutting the injectors down lower - , which then stalls the vehicle.

Worth a try runnig cleaner through them.

For questions 1 & 2 it sounds like either a shift solinoid bad or a gear itself i would have that looked at by a transsmission shop soon and for 3 usually when the tach jumps up and down when idling you have a skip like a plug or wire i would do a tuneup on it and that should take care of 3.
