In XBMC I no longer have 1080p as an option for Resolution, which I had before I was screwing around with stuff. I've messed around with everything so much that I've lost track of when this happened.

I started out with a problem of GDM starting in 1024x768, then I'd manually set 1920x1080@60 in nvidia-settings, and from there it was fine. Within XBMC, 1080p was an option and worked great.
So I did some research and found that gnome-display-properties was setting my resolution to 1024x768, went in and changed it to 1920x1080@60, hit apply, and it reverts to 1920x1080@50. 60hz is an option, but it reverts to 50hz when I apply the settings.
Before I had found out that gnome-display-properties was overriding my settings on startup, I had done A LOT of things to try and remedy the problem to the point that I've lost track of a lot of what I've done.

To make a long story short, at one time I was able to have my resolution set to 1920x1080@60, and have my resolution within XBMC set to 1080p. Now the highest it will go is 1920x1080@50 within X (This is even with manually setting it within nvidia-settings), and 1080i 16:9 in XBMC. It also resets my calibration settings for overscan, which I assume is normal if the resolution changes.

What it comes down to is I want X to start in 1920x1080@60 and XBMC to start up in 1080p. Thanks for any help in advance.

It really isn't 50hz. If nvidia-settings shows 60, that is fine.

Look into DynamicTwinView and set that to false.
Yep, that did it. I put Option "DynamicTwinView" "FALSE" under the Device section, and now xrandr says:
Code:
default connected 1920x1080+0+0 0mm x 0mm
   1920x1080      [b]60.0*[/b]    24.0

instead of what it said before:
Code:
default connected 1920x1080+0+0 0mm x 0mm
   1920x1080      [b]50.0*[/b]    51.0     52.0     53.0     54.0

Now X starts in 1920x1080@60 and XBMC in 1080p, with no loss of overscan calibration settings. Thanks a lot tslayer; saved me another headache.
