Looks like your off to a good start! I thought I'd point you to a recent thread to give you a heads up on cleaning up some details. As I often tell folks, a web site shouldn't just be pretty, it should be smart!. Because you are doing e-commerce you might want to add an SSL, include SiteLock, and if you haven't already install the WordFence Plugin.
@webdiva made some really good points in the thread.
