Somehow I missed this post. This is all completely correct. I deleted mine, as a result. Eh, maybe I could add that you can adjust the chainline to some extent by moving the single chainring you'll leave on the crankset, to the inner position, or even adding spacers into the chainring bolts, between the cranks and the chainring. And you can push the freewheel a bit outwards with spacer rings that you put on the hub. If you can achieve good chainline using either or both these procedures, you can save yourself the effort of redishing the wheel. Which, by the way, will still require you to add/move spacers on both sides of the rear hub axle.
