So if I upgrade to the kk bootloader, and then root with that utility, will my bootloader still be unlocked? What version of twrp should I install? Should I just chill out on stock with root and unlocked until CM11 is stable?

If you took the KitKat OTA, you would still be unlocked. Once unlocked, it stays unlocked since it's a physical change in the phone (blowing an eFuse). You can't set the eFuse to an unblown state. Kind of like a light bulb or the old screw-in fuses for a fuse box in your house. Once the filament in a light bulb breaks, or the fuse blows, it's "blown" for good.
So, once the bootloader was unlocked on your wife's phone, you could have taken any OTA and you would have been safe. No need to go to KK OTA and then unlock it again because it's still unlocked.
You've been safe this whole time.
