Also, consider PVC piping while you have the walls in shambles.
If you lay a pipe or two in the walls throughout the house with pull cables inside, the next time you want to run new cables, you can drop them through the pipes and pull on the pull cables to lay cabling easily, everything terminates easily enough and it's the most future resistant method of cabling I've seen. If you have any interest, let me know and I'll type up a description that isn't so half-assed.
