Be prepared to sleep in the car. If you know anyone along the path, ask to sleep on their lawn or something. Start driving down probably a couple of days out. http://www.eclipse2017.org/2017/maps/whole-us.jpg
Flights New York - Nashville for Sunday - Tuesday (I didn't check Monday evening return flights) seem to go at a bit over $1000, and some still available hotels $300 to $1000 per night.
Could also check prices to fly to some other cities on the path in the map. Kansas City?
