Also when using the gauge type AEM wide band O2 Where does the white wire hook to? [Or how do you hook it up to run with the AEM] When the wide band is hooked into the AEM do you just unhook the regular O2 sensors?

Ugh. Hmmm...
Well, if you are hooking up a alky/water injection to the AEM you could probably use the nitrous configuration to trigger it and control it (and provide fuel offsets to the main fuel map if you want to reduce your injector flow while injecting lots of alcohol).
I assume the kit you are looking at is one of these:

If the Snow kit can see a pulsewidth-modulated signal as a variable voltage, then you might want to use their MAF Variable Controller. You could probably set one of the AEM PWM outputs to send a duty cycle based upon load/RPM somehow and use their controller to control the water/alky flow.
I haven't done it, and haven't researched it - but I would guess you'd want to look in more detail on how that would work. The AEM forum folks might be able to help if you tell them specifically what you are trying to do and what items you want to use to accomplish it.
