Alright, first things first, rise your seat up once long final, place FPM and chevrons in the middle of AoA brackets (which is exactly 14°). Flare gently while idle and extend airbrakes. When the touch occurs, hold your AoA as much as you can (do not exceed limit otherwise you might hit the runway with the aircraft's tail), tap on the brakes, do not apply full brake except below 70 kts, the NSW is automatically engaged below 40 kts and disengaged over 40 kts, so leave it on even in flight. When your speed is about 70kts, use the brakes the put your nose wheel gently on the runway. You can also use differential braking on the very last seconds of the landing if you have trouble maintaining the centerline. To conclude, once your main wheels touch the runway, leave your joystick alone, the FBW system will hold the aircraft AoA, so use your rudder to keep your centerline. Finally, train and repeat as much as you can - circuits training are a good way to get experience in many aspects of flights.
