search in the style.css for this:
#footer {
padding: 0 0 0 1px;
margin: 0 auto;
width: 760px;
clear: both;
}

and set padding to: padding: 0 0 0 0;

and in the header.php search for this:

#header { margin: 0 !important; margin: 0 0 0 1px; padding: 1px; height: 198px; width: 758px; }

and set the second margin to: margin:0 0 0 0;

i hope it helps
