Sorry but I don't really offer any support for modifying Artisteer designs outside of Artisteer. A CSS guru may be able to figure out how to make changes he wants but that isn't something I have time for helping people with figuring out step by step, it is usually a trial and error process. My advice would be if you are not a css guru then get Artisteer and update the design in Artisteer and export it as a new skin. We make the .artx Artisteer files available on our codeplex download page so you can get the art41-wallpaper.artx file and open it in Artisteer to make design changes.
However our instructions for creating designs in Artisteer recommend leaving space at the top for those links. If you don't do that then you will need to figure out your own way to position and style those links which is again not something I have time for helping with myself, though maybe others could help.
