Another example would be
http://www.hom.gb.com/shop/ (for the cart) and
http://www.hom.gb.com/index.php (for example of the regular pages).
If you don't want to do the work yourself or don't feel comfortable with it yet get one of the guy in here to quote for it ( I've used FunkyDunk a few times now) or contact the x-cart support team as they do template changes as well so it fits in with the rest of your design.
