Cloning-wise, this plug-in worked like a charm! The only thing the plugin doesn't do is duplicate the theme folder for the cloned site... so it's pulling all the info from the original theme folder. With that being said, you can't make changes to solely the cloned site - it'll affect both the cloned site and the original.
To try to work around this, I duplicated the theme folder and renamed it, and then I activated the duplicate theme on the cloned site and deactivated the original. For the most part, it worked... But for whatever reason, some of the styling didn't carry over.
