I'm very excited to tell you I did indeed take care of this. Once you have FreeGee (with BusyBox for Required Devices like mine) you can install CWM on the button from FreeGee. From there you do this:
Turn off your phone.
Turn it back on holding Volume Up + Power Button.
It should boot into CWM.
If that doesn't work Try Turning it back on with both Volume buttons and the Power Button.
Once you're in CWM you can make a backup of your current build. (Restore and backup). This allows you to restore everything you have now if you mess it up. Should be your best friend to avoid bricks.
I read it's best to do it on an External SD Card so I hope you have one.
Once that's done you can then install ROMs.
I downloaded the Last JellyBean (4.3) build of Carbon (http://forum.xda-developers.com/show....php?t=2439911) and put it onto the External SD Card. I then Factory Reset the thing FROM THE CWM (that's important). From there, you go to install zip (also in CWM) and install your ROM.
I highly suggest using the Carbon ROM. It's very sleek and clean. I was having a slight battery draining issue with it but I just changed the CPU Governor and I think it's a lot better now. You can also install the gapps (DL here http://goo.im/gapps The 4.3.0 if you're using the JB version of Carbon, I suggest it over the KitKat since the KitKat build has yet to be FULLY functional.)
Hope this helps (: If you need any more help I can try to help you.
Ok Heres what it is. When I hold Vol up + Power, as soon as the first LG symbol pops up I let go of vol up while keeping power button held and the screen goes to where it says "secure boot error device unlocked so boot ok". Then it goes straight to CWM.
