Appearance Setting Issues

I have just recently down loaded the Frame Market theme and I'm having some appearance problems. I can not get it to set the background color or image to what I've assigned, I am also having problems with my header image getting stretched (cuts image off) more than what shows on the preview when I upload the image.

I am also having a problem with my product & menu pages but I'm not sure if this is a Theme issue or Plugin issue.

Thanks!
