Can't help with airport suggestions, we drove in when we went a few weeks ago.
VRBO.com for lodging. TONS of condos on the beach there. It's out of 'prime' season now so prices have come down a lot from where they were just a month ago.
I really like the Hilton Garden Inn there. Friends recommended it and since I've met several people that always stay there for annual family vacation. It isn't a new property, but the facilities are good and it's right on the beach.
JKA for sure on airport. It's busy for an un-towered GA airport, but a mile from the beach. That's my go-to for an afternoon shrimp run. Make sure to eat some Royal Reds while there.
