$2000 for foam insulation? Not even. That's something in the range of $7500. An R38 layer of blown fiberglass is more in that range. So that's what we'll go with. The fellow who'll install that insulation will manufacture caps for the recessed lights, which should provide some sealing.
The duct guy has been here and will start work on Friday. New ducts are of better material and will carry this house many years forward.
Ducts, insulation and windows, in that order.
It's a fair dreadful time to do these things, because we'll have the air-conditioning down for days. But when the summer really heats up, we might see some savings.

UPDATE: From what I understand, the house in Nashville is about 70 years old. It would be interesting and enlightening for the Gores to detail the steps they're taking to make the house more efficient.
