Featured Content image alignment

I am loving using this theme and would highly recommend it to anybody looking for a nice clean professional theme. However with that said I am having a few minor issues with the most pressing involving the "Featured Content". Problem number one, the images I have set for the Featured Content are not centered. Problem number two, the images for the Featured Content are displayed in a vertical fashion instead of horizontal on iPhones or mobile devices. www.casehardintexas.com Thank you in advance!
