Near the door to my front porch is a double switch. One controls the light in the center of the ceiling in the living room and the other controls the front porch light. Just inside my bedroom are two switches. One controls the switched outlets in the bedroom and the other is a 3way that controls the overhead light in the hall outside the bedroom. Is the logic that the switch nearest the door should control the lights/outlets in the room where the switches are located? If so, the porch light would be away from the door in the living room, which doesn't seem right. How should two switches be arranged?

I was replacing phone lines in my house, and when I got to the terminal block in the basement, the green and red were attached to their respective posts, but the yellow conductor had been attached to a grounding post that is grounded to our water pipe. The black conductor wasn't attached to anything. Is there any logic to grounding this yellow wire? If I were to have the phone company put in a second phone line, that would use all four conductors, and I certainly wouldn't have a ground wire then, so I'm questioning if that wire should even be connected to ground. Thanks for any input
