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

Hey I absolutely love this theme but I'm also having cut-off issues in gnome shell 3.4. The icons get cut off along the top and left hand sides of the application menu and the text gets cut off after only a few characters, also feels like the icons are too big now. Also the text for the favourites bar comes up black which is hard to see on the dark overlay that gnome shell puts on top of the desktop. I would've taken screenshots of this but I couldn't work out how so here's some images taken from my phone (poor quality but it shows the problem).

(please note this is not criticism in any way, everything worked fine in gnome shell 3.2, it's just the update seems to have messed your theme up)
