The DC-10 is a very easy aircraft to land. I agree that 50° flap is a good idea on a wet runway although it does cause a little bit of airframe vibration. I personally never used auto-throttle for landing in order to avoid floating down the runway.
In a crosswind it was a beautiful wing-down machine.
It was normal to flare and take the power off at 30 feet. If you flare too high for any reason then it might be necessary to squeeze forward gently on the control column.
