Have you signed up for the forums over at ED/DCS? There are PILES of HOTAS files/configs available over there for every make of sticks out there.
Welcome to DCS world, it's a lot of fun, takes some time, but it's rewarding. A10C is still IMO the best of the bunch, you'll love it once you get online too. Flaming Cliffs 3 is one you should look at, the sale ends today I think on it too - great value, lots of planes, it's a little bit lighter than A10C avionics/etc wise, but the F15C and SU27 have had recent updates to the FM and other stuff, and it's a blast online in large servers, or just in the offline missions you can get. There is a spot on the DCS homepage you can download custom missions, campaigns, and the like that others have created too.
Wolfala here is a good person to ask about A10C too if you run into any headaches.
