As for FDX's landing technique, I cannot comment but they have been operating the type for a hell of a lot of years/hours and one would assume that if there were systemic deficiencies in their prescribed landing techniques, there would be similar incidents, if not accidents.
FedEx has suffered a significant number of landing incidents, including 3 hull losses.
The rule is: you "bounce", you "go around". (Trick is in the go-around, pitch attitude <10deg NU until 35-50ft RA, otherwise you will get a tail strike).
Depends on the severity of the bounce, but generally speaking you are correct. In some cases, maintaining the landing attitude (not adding additional pitch) and adding a bit of power will permit a successful landing. The MD11 is not a difficult airplane to land. It does however require strict attention to proper technique and a stable approach.
