The suggestion by Amir concerning my first question worked. Thanks Amir.
It also gave me enough of a hint that I figured out a solution to my
second question, although it seems like a hack job. I define a new claim
environment with the \newtheorem* command and put a \ref to the original
claim in the name. I figured this out by reading a pdf file about the
amsthm package that I found with a google search.

I have attached a lyx file that answers both of my original questions.
Thanks everyone. This is a great list.
