Lamboo1, the retract 2 steps procedure was added at some point. Came with a JAR change, I heard.
shortfuel, any overweight landing is an emergency, since you're violating a limitation of the aircraft prescribed by a FAR (landing loads in 25.473, though it's technically 25.1519)
In any case, landing distance will be adequate with your takeoff weight and configuration. RTO performance is limiting in that regard. The limiting factor with almost all airplanes, and I know on the Airbus, is single engine missed approach climb gradient (FAR 25.1001 and 25.121d).
The urgency of the emergency (for medical emergencies and bomb on board) should be weighed against the probability that you will need to conduct a single engine go-around at a low altitude.
