Rebranding Wordpress MU Challenge

Here is the list of files that needed be replaced manually:

wp-admin/images/logo.gif
wp-admin/images/logo-ghost.png
wp-admin/images/wordpress-logo.png
wp-admin/images/wp-logo.gif
wp-includes/images/wlw/wp-comments.png
wp-includes/images/wlw/wp-watermark.png
wp-includes/images/wlw/wp-icon.png
wp-includes/wordpress-admin-bar/themes/grey/images/background.png
wp-includes/wordpress-admin-bar/themes/grey/images/background-logo.png
wp-includes/wordpress-admin-bar/themes/grey/images/bullet_arrow_down.gif
and maybe wp-includes/wordpress-admin-bar/themes/grey/grey.css

I have found 1 problem, there is no folder in the wp-includes folder called "wordpress-admin-bar"?

WPMU version: 2.9.1

Any advice would be great!

Thanks,

Anders
