so - if we have some method of knowing that the universe is expanding then I would guess that we have some notion as to the general shape of the universe and it's center? can someone show me a pic of what it looks like? Does it look like a moose with cheeze in the center?

It has no center..for the same reason that the surface of a balloon has no center. There's nothing on the inside or the outside of the balloon, so you could say that the universe looks like the surface of a balloon, but not the whole balloon.
