How do I find out about the black market suppliers for Tingalf?

Where do I find Tutamun? I talked with him very early on and I don't remember if I killed him or not. If not I need to find him again to complete the quest about the killing of George.

I got back to the burning cart too late with the wheel. What do I do now?

Is the Dwarf Mine Shaft in the area of the Orc Camp the same mine that you are suppose to enter inside the Drarfen Village?

Thanks
