If you have the menu items for google sitemaps in the admin area I'd assume the SQL patch installed correctly.

The rest of the files are to go into the root directory. This mod will not work without them. After you copy the files into there - you may need to change the permissions on the 4 .xml files. (before resorting to using 777 see if it works as is after just copying the files into the root directory)
