Hi, I see your menu across underneath the header image right now.
I see you have the fonts larger now in your menu. To make the menu labels bold, add the following to the #menu-primary li a rule you have in your custom CSS.
In fixed width themes, you can move one of the footer widget areas up and to the left of the content, but on responsive width themes, such as Origin, this is very difficult to do since it requires position: absolute; which means the sidebar would not flow and adjust on narrower browser windows or smaller devices such as tablets and phones.
You can use the widget visibility feature to set which widgets will appear, or not appear on which pages This support document explains how to do that.
