For the footer, you might experiment with Site Admin | Appearance | Additional HTML. Yep, kind of a strange place, but what I put into Before Body is Closed let's me create a custom footer. This dialog box seems to accept HTML, so you might need to design your footer in the editor, switch to HTML view, and then copy/paste this code into the Before Body is Closed dialog box.
