Using Nice_Menus but can figure out how to position it

if you look at my site http://www.fansportsunion.com/fan/ you can see that I put the menu in the header I know how to move it around with in the header. But my problem is this - you can see that I have a banner in the header as well is there any way that I can Position the menu to the lower left and the banner in middle right of the header?

here is the code that I change to move it around

}

#header-region {
  position: absolute;
  top: 30px;
  left: 20px;
  height: 38px;
  line-height: 28px;
  vertical-align: bottom;
  padding: 0;
  color: #F1F5F9;
