Well, I can't answer your first question, but as to the second one, I do have a few things to say.
We all must remember that Sauron was not just a big eye like they say in the movies, that's just all that was visible. He was there, just not embodied.
Personally, I think that whoever captured the Ring(say a Nazgul) would have brought it to him,(I wonder if they could see him?)and he would have picked it up and put it on his hand. That's my opinion, someone correct me if I'm wrong.
