Wireless is nasty, it's what you use when it's impossible to run copper. All concerns raised about black spots, dropping data rates, regular dropouts and having to hold the laptop at a 45 angle while you stand on one leg and move it in small circles are very real, and get worse as speeds go up. Moreover, latency with wireless is more of a problem with data rates - you might be able to transfer a file reasonably quickly at a theoretical 54Mbit, but it takes an extremely long time to request the file. If you're making lots of small requests with lots of small responses - for example, webbrowsing, gaming, streaming media, etc - your apparent speed goes to hell. Then there's the security and configuration problems. Forget it, run wire while you've got the chance.
For the data and TV, you can DIY - get a 100m box of cat6 and 100m of Belden RG6, some wall plates, one of the patch panels you've been offered gratis, a punchdown tool, an F-type crimping tool and crimps, a bag of cable clamps and a TV splitter amplifier with as many ports as you've got rooms. Your nearest google search will answer every question you could possibly have on how to hook them up. And no, the data isn't being connected to the phone network, because the router is isolated.
The phone and power are legislated, which means you're not legally allowed to do them yourself. For power, you've got to get the sparky, but $2k is ridiculous. For phone, it isn't any more difficult or dangerous than wiring the data ports, it even uses the same outlets, and, unless the wiring is coupled to the mains and blows up an exchange, no one is ever going to care or check who your phone wiring was done by. Not that I'm suggesting you do anything naughty, of course.
Yet another option is that you could use a sparky for the sparking stuff, and a data cabler for the phone/data cabling. They're only as qualified as I earlier suggested you become, and hence should charge significantly less. You might need to show them what they're doing wrong a few times, but at least it will all be legal.
EDIT: yep, I agree with stu, except the bit about going cat5 instead of cat6. While most of the time cat5 is fine for most applications, you simply can't do Gigabit over long runs with it. Even then I'd agree, but the difference in price between cat5 and cat6 is so small that there's really no reason not to get the better cable.
h34r: I keep hassling my bosses to get a mobile net connection but they are too tight to provide it. I guess all I really need to do is drive another block or so and find another open access point, free internet sharing for all I say. Just lucky I am not into torrents and all that bandwith hogging stuff. I can imagine conversation now, uninformed computer user at home notices their internet has slowed to a crawl so calls their ISP to complain, the ISP say you have been downloading bla bla bla and have now been shaped. End user at home says no I have not I've only been sending emails, the car parked outside their house drives quietly away, next victim chuckles the driver (insert evil laugh here)
