Thanks all!I now have Mutt running with all my mail in it. I don't know if it's set up properly, or how to use it, but now at least it's just one program to learn instead of 3 or 4.
I was directed off-list to the following link which may be helpful to others:
http://www.dcs.gla.ac.uk/~lativyn/articles/debian-mutt/ I guess I'd have found it by searching the archives more thoroughly. Cheers, Tyle
