1. Yes, basically correct. I have heard one year to qual on the 340 but that may have changed. Notice below though, if you chose to go to the 380 and then upgrade on the 330 rather than just sticking it out a little longer on the 380 for upgrade on that, make sure you get at least 700 hours on that aircraft at Emirates before making the move to the 380.
The minimum requirements for upgrade to command on the Airbus
-A330/340 and B777 fleets for A380 First Officers are:
-6,000 hours Total Time
-2,500 hours Emirates operating time and 3 years’ service in
Emirates, on any fleet
-700 hours Emirates operating time on the fleet on which the upgrade
is planned
-2 years from the date of successful completion of initial PPC on the
A380.
Minimum Experience for A380 Command on Type
-6,000 hours Total Time
-3,000 EK hours of which 2,500 hours must be on EK A380
