I haven't networked anything but am going to do that to my computers and printers, plus a tv later. Can I get a good reference book or where should I go to get this done?

I am going to get a new desktop and laptop in the near future. I will get a hdtv as well, but later. What I would like to do is to network my desktop/laptop so I can use the laptop anywhere. I will network the tv later. I am looking for reference mags or companies that I can rely on to get this done. thanks.
