I think the 5200 was the landers total velocity. The command module orbital velocity was 5300 ft/sec, so the lander at 5200 ft/sec would be lowering its orbit. Not a vertical speed, thankfully.
Regarding a possible autoland, I once worked with a coder that wrote software for the space shuttle autopilot. The space shuttle had a full autoland capability, however, it was never used on any flight. The pilots didn't train for 5 year to let the computer do the possibly only real landing they may get.
I wonder if the Artemus crew will have that option.
