Can't help you there, when i was looking into it, it was for my Dodge Diesel.

Yea, there's a lot to learn about it. I'm not even going to bother reading until I get to that point. I have too much to do before I have to worry about it. My engine will be built and installed plenty before I get the methanol kit.

You don't really need to turn down your fuel delivery - the purpose of the water/methanol injection is to reduce the heat available by using a good portion of the leftover heat of combustion to vapourise the water and methanol (which also has the nice side-effect of steam-cleaning your combustion chambers.) The methanol helps to "fire" the fuel in the presence of the water, so you're not "damping the fire," so to speak. Turbos on boost like to run a bit rich anyhow - especially if they've not got a charge-air cooler in place (what you're calling an "intercooler.") When you compress air, it heats up - which is why you want to take the extra effort to cool things down some.
The water/methanol fog can be introduced through an additional set of "port injectors" at or near the intake ports on the cylinder head, or through the use of a "fog plate" between the throttle body and the intake - it's up to you, and how much fab work you feel comfortable with. You can also use denatured alcohol instead of straight methanol - which might be easier to find (either or both will be readily available at your local hardware store - "denatured alcohol" is simply ethanol with a significant percentage of methanol added anyhow, to avoid taxation by F Troop.) Since you won't have manifold vacuum, you'll need a smallish pump to force the fluid through the fogger - in a pinch, a windscreen washer pump will usually serve (but may not last long -they're not designed to run all the time.)
