This doesn't give me any information about what isn't working at this point. If you have the nvidia driver installed, nouveau blacklisted, and KMS enabled then the driver will work just fine.
Unless something is creating an /etc/X11/xorg.conf file, or a file under /etc/X11/xorg.conf.d? Specific configuration files aren't needed for the majority of systems, generally only to do things like enable CoolBits.
It can only be this step that's failing to work correctly, for whatever reason.
You could try a fresh install, update, then install the drivers using the steps I've outlined in this thread - it's actually trivial to install them "manually".
@jonathon - Fresh install and doing the install manually appears to have done the trick. Everything appears to be working as expected now after just the sudo pacman -S nvidia-dkms nvidia-settings --needed and not using the "Hardware Configuration" screen.
I appreciate your help here!
PS - Apologies for the delayed reply, apparently noobs can't post much in the first 24 hours
