I don't use OCC so I don't know what it does when you click scan/browse, I do all my edits manually with plistedit pro.
Looking at your error, I think it added 2 version of voodooInput.kext, one from Voodoops2controller and one VoodooI2C.kext to your config.plist.
Disable one and it should fix the problem.
Yes, you should disable the BRCM kexts from config and remove from kexts folder as well. No need if you have an Intel BT/Wifi combo
Give this a try
config-4k-Intel.plist.zip
