"Oh, and one other thing, does Lexington have a decent sized airport or only one for commuter planes?"
Lexington has an airport. I'm not sure what you consider "decent", but it meets the needs of the community. Many people will choose to drive to Cincy or Louisville though for cheaper rates. I, myself, have never found the rates of those larger airports to be worth driving an hour. You will find a variety of sizes of planes that fly from Bluegrass Airport.
Here's the link for the airport. I think it's ok to post here?

Unfortunately, I know nothing about Raleigh, so unable to help compare for you. Sorry!
