A pair of "Ultra" book should run you less than $2,000 all told. I'm sitting here typing on a Sony Vaio Ultra Book that cost me $700 last year, and except for the low res screen (hey, pay for what you get) I've got no complaints. I can play DOTA 2 at medium settings, smooth as butter while something simultaneously streams to a nearby PS3. These things are sleek, high performance, and well worth the money. If you're a big gamer you could get one with a dedicated Nvidia mobile card and not even bother with the desktop.
As for a camera, since you just mentioned it offhand I'm guessing you're not big into photography. So it really depends on what you want. If you're up to spending $500-$600 you can get a Sony RX100, a perfectly pocketable camera that will get you photos equal of a somewhat older professional DSLR. It's that sharp. If you're not that into it, then honestly modern high end smartphones are getting good at this stuff. An iPhone 5 or something similar (go to engadget for reviews) will net you "good enough" photos. Or, alternatively, if you wanted to start photography as a hobby you could pick up a Panasonic GH2 or Sony NEX mirrorless camera, which will give you all the manual control, features, and often image quality of a DSLR without the cost.
As for a TV, honestly it's so competitive you just select your size and price range and look over a few reviews. Companies are at razor thin margins for HDTV's so one or two (or whatever) excellent ones can be had for a good price all around.
Hmmm... speakers are speakers. Bose are overpriced so get something else for half the cost that's just as good. But otherwise I think that about covers it. Like I said, don't bother with a desktop unless you REALLY want one. I've got mine sitting, disassembled since I moved for 2 months now. Haven't used it thanks to my cool laptop, though that may change if I end up getting Crysis 3. Which is why I suggested a dedicated Nvidia card.
You could always stream stuff to your tv's and ditch a cable/satellite service entirely. A Roku is extremely user friendly, and between Netflix and Hulu Plus you'd have a good selection. Even better if you've certain proclivities visa vis copyright. A fast internet connection can do wonders, and PS3 media server makes it supremely easy to stream things to a 360 or PS3, or any DLNA device so far as I know. Not to mention most new laptops have HDMI out on them.
Anyway, that's all I can think of. Good luck!
