YAY.... It's finally over
I'd like to thank everyone that tried to help me
I managed to fix my problem by restoring my old display settings. I did this by going to "/etc/X11/" (thank you tashiro for showing me that log file which directed me here) to find the "Xorg.conf" and "Xorg.conf.backup" files. I deleted the "Xorg.conf" file and renamed "Xorg.conf.backup" to "Xorg.conf". This seems to have restored my settings prior to setting up my second display. There was probably a nicer (safer?) way of dealing with this, but you can't argue with results.
Also, I set up (or tried to at least) my second monitor by clicking on the hat (does it have a name?) at the bottom left, and going to system settings. I then clicked on the "display" tab. Under display there is a tab called "dual head" which allows you to set up multiple displays (maybe I could've been clearer if I had all this info sooner, but I couldn't get at it since gnome wouldn't load).
