Add this to your additional.css and adjust the numbers to park where you want it. (I copied that straight out of my additional.css so the numbers may have you looking for your toplinks at first.)
Code:
.toplinks {
position:absolute;
{vb:stylevar right}:{vb:math {vb:stylevar padding}*2};
right: 400px !important; /* changed by andy added */
top:250px;
color:{vb:stylevar toplinks_link_color};
font: {vb:stylevar header_font};
text-align:{vb:stylevar right};
}
