Another IE-FF problem

My new page was designed in FF and looks just as I wanted it, but when I tested it in IE I had two problems. First is that my Navbar isn’t lined up properly within the page. It is pushed off to the right a bit. Also, at the bottom of the page a little bit of my background is sticking out under the image I made to close off the content box. Does anyone know of solutions to these problems?
