To Spawn your npc, open up the Rendering window to the place you want him so spawn (e.g. The Bannered Mare) and drag <your npc's name> from the object window into the rendering window. From there you can move him around using the right and left mouse clicks, while using shift and middle mouse to angle the camera. Hope this helps.

Also quite interested in this, as i havent been able to find Tuts on this anywhere.
