It all sounds about right. Also, since it took them so long to close
the thrust levers, I'm guessing this was not a flight crew, but a
maintenance crew. The parking brake is either on or off on that
airplane.

Before or after the crash?

They disengaged it and used the toe brakes 11 seconds before impact.

On the 737 pressing the toe brakes pops the parking brake off. Could
be the same on the Airbus.

No, it isn't. The brakes are a different system completely on the 'bus. The
737's (and in fact all Boeings) is very similar to the Cessna's system as
far as the pilot is concerned. The bus uses a different hyddraulic system
for th eparking brake and it's almost completely independent of the toe
brakes.
Besides, they weren't an issue in this accident.
