Detailed walkthrough
The key for the electric switch is on the semi circular bar up the stairs to the left as you go through the casino door. It is not a key key, it looks like a piece of paper or a clipboard, it is where the marker points but it's hard to see, (lot's of people have been saying it's a random marker and they can't see anything, but it's there.)

The key mentioned above is actually a code for the security computer in the rooms past the bar area, the computer then unlocks the electrical switch.

Shutting off all three gas valves isn't incredibly difficult: turn off the one near you as you enter the area, then get the one behind Dog/God's back in the room on your left, then, as he is walking toward the far end of the kitchen, get to the last switch.

When you speak to Dog/God, passing speech checks of 50 and 85 can get him to merge his split personality. Doing so will net you positive karma. He'll become somewhat amnesiac from the merger, however he still realizes that he's grateful to you though he doesn't remember for what exactly.

Bugs

 * If the key/note is not read in the pipboy before "opening" the security terminal the option for opening the electrical closet door will not apear.


 * If you enter the room where dog is while your collar is beeping, it will continuously beep throughout that room and their is no way out of it. A way to fix this is to go to a previous save file and reenter the room without your collar beeping.
