Did the Midland definitions of up/down remain after grouping,

They remain to this day. Changing designation would be a fraught
task, I can see why it would be put off even if it was thought to be
a good idea.

Lines presumably change designation somewhere in Derby Midland
station. Perhaps there is some sort of object which marks the spot.

There is - milepost zero for the west line is clearly visible at Derby South
Junction.
