[MENTION=469087]coupdegrace[/MENTION] - I think you got it right. The hub and location of the sprocket are fixed. Determine distance from center line of the bike to the outside or inside of the sprocket then determine the right BB and Crank to match.
I was surprised how sensitive my SS was to chain line alignment. I had to play with sprocket spacing and wheel dish to get it right.
