So just make sure were clear, it's going in the main house, and it's heated and cooled and your living in it? The reason I ask is if it was something like a summer home and no one was there it's not a good Idea to be putting in real wood floors unless it's going to have a steady temperature.
I still think prefinished hardwood or engineered wood would be a better value, last longer, way faster to put in, no sanding, no having to go buy stain and sealer, no odors or dust.
Nail down and walk on the same day.
I would just use rosin paper and a real flooring pneumatic nailer with staples or L shaped nails. Never glue.
