Go with the "basic" install of the NWNCQ project. It gives maximum visual effect with minimum inconvenience. I've combined that with several other monster overrides I'm using and put them all in a single rar file below. All you have to do is extract the files into the "override" folder in the "nwn" directory and you're up and running. If you place the "override.rar" file in your "nwn" directory, right click and and choose "extract here" the files should be extracted automatically into the override folder.
