1280x 1024 screen resolution IT_shop template

I have been trying to get the it_shop template to spread across the screen with 1280 x 1024 screen resolution. I have it almost working but he middle column seems to get smaller instead of filling ion any gaps. I am eding the layout.css file and want the middle column to automatically fill in any spaces. I have attached a screen shot. Please help I have been wrking on this for days and it does not seem to make sense.
