Distant lights can be moved, but there's no point in doing so (except to get them out of the way) since they actually shine from "outside" the scene - only the direction in which they point matters.

Copying coordinates from a prop can work, but some props are modelled away from the centre (so they are at a distance, but their coordinates are still (0,0,0)). The Align plugin can be a big help here, but you are going to have to fine-tune the placement by hand at the end unless you are very lucky.
