As for level editor and world editor.
Level editors are generally indoor area editors, sort of what you would find in an FPS alot of the time. World editors are usually the whole deal, or mainly focused on outdoors.
Lightmapping creates a texture that overlays all other textures in a map, and creates what are known as static shadows, since they won't be upsating or changing when things move.
A 'Shadow system' manages shadows on dynamic(oposite of static ;)) shadows. Things like players, and other moving objects.
Theres no overview I've found for this stuff, it's just things you pick up along the way.
