Re: telephone wire
I dont trust wireless, no matter what card/AP combination I have used, if you walk in the wrong spot, your connection can lag out. I wired up my entire house with two phone, two data (cat 6) and two RG6, split onto two boxes on opposite walls, and a few certain rooms with additional connections for distributed audio, all home runs down to my basement. I ran all the wire and terminations myself, and the raw materials only cost around $350, but since, we bought a TiVo which uses the ethernet jack I put behind the TV that my mom said "oh we'll never need that there, we're never going to have a computer back there". Whole house wiring has its benifts considering more and more appliances are coming out nowdays with ethernet capability, and you'll never know where you are going to put those things when you get them.
What it all comes down to though is what you think you'll need, then put in more than that just for safteys sake.
