I would say you have a pretty good plan. I think the fall planting is a good idea - lets you get ammendments added and cut/destroy existing plants. When planting in the fall weed competition is the lowest and conditions are usually favorable (not too wet, not too hot, not too dry, etc.). Late summer/early fall is the ideal time for no-till seedings (in NY). Spring is good also, but weed competion is aweful high.
