The "r" fsh is only used for reflections. It's so small, there is no reason to edit it. So, just use the large.
You should copy your created cyberface over the extracted dds file because it already contains an alpha. If you save the face you made as a dds, it might end up real shiny in-game because the alpha defaults to white if you didn't create one. Also, when I am trying to save a dds that I created an alpha channel for, I get the error "too many channels to export" or something similar. When you save as a dds, make sure to use DXT3 as it keeps the filesize low, but keep your original cyberface as a psd. Happy patching.
