Issues related to hardware problems
You are still using the 'nv' driver for your nvidia card. That's nouveau. Perhaps you meant 'nvidia'?
This is just what was created after reboot, where would I change that?
It's in your xorg.conf file that you just posted.
It seems you also haven't taken the advice to use elrepo's rpms. Otherwise your Xorg log would show a different kernel command line.
Since we are using Rocks Cluster I wasn't sure of any conflicts that might happen enabling them, as for example. kernel-devel was already there and enabling elrepo caused another kernel-devel to install.
I see now, I added

, I'll have to check when I'm on site if either the NVIDIA card's DisplayPort or in the internal VGA now work. That's all I really care about.

The driver rpms from elrepo don't require kernel-devel at all. Only rebuilding from the source rpm requires a kernel-devel package. You are of course supposed to deploy the ready-made binary rpm. It will also contain an xorg.conf to which you just have to add the BusID line.
Your addition of 'nomodeset' won't make anything work.
Sounds like you enabled the disabled-by-default elrepo-kernel repo and were being offered their kernel-ml packages. That repo should be disabled unless you want to change kernels.
After a reboot, I am at least now able to use the NVIDIA with the bare bones non-GUI console. Running startx fails with:
The internal VGA still does not work, black screen.
