1.  He won't do anything as emperor, as he was never scripted to become emperor. He was just supposed to die (you weren't meant to be able to kill Mehrunes Dagon)

2. I honestly have no idea, although apparently it is more effective to use the Wabbajack

3.  I don't think he leaves a corpse; it says on the wiki page that he just melts. He most likely has nothing to loot.

4. Aside from being able to use Mehrunes' Razor on him, no.
