In reality just pulling back the side stick will do the trick. This will disconnect the AP and rapidly raise the AOA, which will give you TOGA thrust, which will automatically stow the speed brakes. Slamming the levers forwards though will give you the thrust marginally sooner and is part of the general Airbus escape manoeuvre of stick slammed back and levers slammed forward. The array of computers and sensors will give you every last ounce of performance available.
That is great technology. What about when the speed is at minimum for a given flap configuration, say whatever is required to fly the CTL downwind at 150 KIAS. Presumably, the aircraft was at 2510, msl, and had to clear terrain that topped out at 4,000-4,300, msl, or thereabouts. The terrain would have been unknown to the crew until the EGPWS/TAWS started its first stage of alert.
