Clarifying a few electrical points.
I am completely rewiring my house, so I followed the standard advice and got Wiring Simplified. I have read it through and still have a few questions.
1. I know that I need to staple the cable to the stud as it runs down a wall. I am also running through a couple studs to a new duplex outlet. The new outlet is only a couple inches from where the cable comes through the stud. Is this considered secured, or do I need to still staple it some how?
2. The book tells me that I can reidentify white as black to a switch, then later tells me that I should have a free white at a switch if possible. The only place I have a problem with that is on a three-way switch. Do I need to go back and redo it with 4 wire cable?
3. All of the old wiring runs through the attic and crosses it in several directions, without protection. I saw in a post on here that I can run cable straight across the trusses, but the book tells me that I need to put 1x2s or some other form of protection for the cable, even in the attic. Which of these is correct, or more likely, how am I misinterpreting what I read?
I think that is all of my concerns, for now. Thanks for the help.

You should staple it down anyway just to be safe.
I would follow the book using a 4 wire cable.
I would suggest protection although in the attic you may not need it, all depends on your exact case.

If you change the wiring scheme you will have a neutral at the switch without needing special cable.
It will be easier to insulate the attic with organized cables instead of a spider web. Is the attic accessible?

@pcbosa The attic is semi-accessible. It is about 4 foot tall at the peak. I am doing most of the work on my knees up there. I plan to blow in insulation when I am done with all of the other work.
The three-way is on a dead end. Is it necessary for me to rework it? Is the neutral wire required?

@Abolos. If I can't easily staple the cable, what other method would be acceptable for securing the cable with a pvc box?
What circumstances would allow me to forgo the protection in the attic?

When you create new three way switch circuits.... if you bring the power into one switch and take the lights out of the other then you'll have a neutral at both ends.

With the attic that low it would not worry about thee cables too much. Staple where you can reach.
