How does expansion of a MOA for operations above 10,000 feet in New
Mexico relate to a mid-air collision in Florida on a low-level
training route?


The Florida midair did not occur on a low-level training route.



You might also note that aircraft below 10,000 MSL (except in some
special use airspace) is already restricted to airspeeds below 250
KIAS.


That's not correct. Aircraft below 10,000 feet MSL cannot exceed 250 KIAS
unless the minimum safe airspeed for any particular operation is greater
than that speed, the aircraft may then be operated at that minimum speed.
