[ubuntu] Theming & Tweaks

view story

http://ubuntuforums.org – I am trying to get this theme installed. http://gnome-look.org/content/show.php?content=148398 I copied the content into the folder, but nothing happened. Also, there was a sudo apt-get install command (i forget what it is now), but that couldn't find the package. Anyone know how I can install this theme? Ubuntu 12.04, Unity. Also, I saw in a few different screenshots, that the people have there devices/mounted drives in nautilus on the bottom instead of the top. How do I accomplish this? (Hardware)
