I could probably live with some overlap, I always have.
I DO have 650 wheels.
I can get shorter crank arms, but they have to be specially made. My thought about them is that I will have to be spinning faster to keep up with everyone. Is that right? I'm in pretty good shape, but I'm more of a hill climber than a fast spinner. And it seems that my spinning is getting slower and slower. I do work at it, but it's those fast twitch muscles (or is it slow twitch) that you kind-of start losing when you get into my age cat!
