1/ well in this case training is available for "rejected landings" after touchdown if the Airline Flight Ops Dept chose to do it. Ours does and has done for over 10 years. I last did it about 12 months ago in a Sim session in RJTT.
2/ Once you are Airborne the Config Flaps warning stops, then push TOGA and commence the SOP GO Around calls for your type.
