From a software load point of view, can the current orbiter computers
hold all of the software used between de-orbit burn and full stop on
runway,

Yes, although several mode changes are required.

Are there any plans to let the orbiter land itself on upcoming crewed
flights (with crew manually deploying landing gear and air data
probes) to really prove the software can autoland the orbiter in real
life ?

No.

How much ground control would be needed once de-orit burn has been
made until the shuttle comes to full stop ?

Mode GNC computers to 303
Take GPS data to navigation
Mode SM computer to 201
APU press/start
Maneuver to entry attitude
Mode GNC computers to 304
Deploy air data probes
Take air data to guidance/control
Arm/deploy landing gear
Arm/deploy drag chute
Close fuel cell reactant valves

Assuming an empty orbiter doesn't self destruct and lands perfectly.
Would there be any issues with there being nobody inside to turn off
systems before ground crews can open the hatch ?

RCO has the capability to close the fuel cell reactant valves, which will
suffice for a quick-and-dirty emergency powerdown.
