Autofocus - can I move sidebar widgets from the bottom to the side

Autofocus is a really nice theme for image driven Blogs. All I really want to do is change the layout so the sidebar "widgets" are down the side rather than at the bottom. I looked in home.php but I cant find any code at all that displays the sidebar but somehow it magically appears (or maybe I just dont know enough about php). I also looked at the sidebar.php and it seems to have CSS styles "primary" and "sidebar" yet I cant find these styles listed in any of the CSS pages???

Any help pointing me to the right spot to alter this would be really great.
