Please avoid a manual install and use the GNOME Tweak Tool, it's much easier.
You can use the gnome-shell theme extension for easier switching of themes.
GNOME Tweak Tool
Make sure you have user-theme-extension installed. Load the GNOME Tweak Tool and go to Shell Extensions and click the "Use Theme Extension" switch. Now go to "Theme" and click the Shell Theme box and locate your theme zip. Now you can select the theme in the dropdown box. Make sure you selection the right version for the GNOME version you have, otherwise the theme will not show properly.
If you run GNOME 3.4, just extract the 3.4 version to ~/.themes

Compatibility: GNOME 3.2/3.4.
Update - 1.1 - Sun 15th May 2011
- Fixed padding on calendar day - Fixed Intl switchers pointing the wrong way.. - Fixed submenu background colour for when the menu has a long list(i.e network manager). - Better URL highlight colour.
You say you don't use GNOME anymore, may is ask why and what you use instead? It's just because I liked your themes very much and I'm very sorry they won't get updated.
many thanks for sharing this one with us and for the 3.2 compatibility.
this is really a beautiful theme!
