OT- Any electricians out there? 4 car garage!!, California code if it matters. Options

[Andyrew]

Any electricians out there that can help me with a couple house wiring questions. We're in the closing stages of building our garage add-on. My FIL is a journeyman electricain, but doesn't do Residential and therefore doesn't know the codes.

We're putting a new 200amp service outside the new garage wall that will feed the existing 125amp inside the new garage (outside the old garage). I suspect that will need to run in conduit (or should). My FIL wants to know if we can run 3 #2 wires to feed that old service. All the new wiring will come off the new 200amp service.

Questions about the garage and the Laundry room wiring.

How large do the holes need to be?
Do we need Conduit?
What is the minimum per wall? (we'll probably add more later)
If I put more per wall do you think it will raise concerns of (re)doing electrical calculations?

I know they all have to be GFI protected.
One of my research studies states that only the first in a string needs to be GFI the others can be standard and will pop the first GFI that they all go thru. Something like this.

I think my other house was like this. Outlets in the front of the house would pop the GFI at the back Patio.

Do I need to put an outlet on the front car door mini walls?
I'd like to put an exterior outlet there...

Any help would be appreciated. We're getting close to shelter around the Porsches. (IMG:http://www.914world.com/bbs2/html/emoticons/mueba.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/mueba.gif)
