Correct. If you're putting stuff in a closet far away, a cat5 wire can carry that IR signal, too.
How does my XBOX controller talk to my XBOX with that solution?
It doesn't. Xbox / PS3 controllers are RF / Bluetooth, not IR. The console must be in range of the controller.
I see that Logitech released a new harmony remote.. how does it work? It says that with the media hub you can control devices in a cabinet or through walls, etc. Is the remote 802.11 or something?
Yes, and RF.
Because it may not work in all cases. HDMI runs over 25' can be problematic without specialized cables. This one does have an equalization chip built-in (don't know if it's a Redmere cable or not - which would be one of the recommended solutions), so it's certainly better than a 'normal' cable, but it's still a pain to deal with.
What is the advantage of the HDMI-over-cat5e-extender?
It will work. And the HDBaseT versions also solve the IR repeating problem and provide Ethernet connections (optionally) all at once...
Any recommendations on a specific type of speaker wire for those speakers?
Monoprice in-wall rated (CL2 or CL3) speaker wire, 14AWG or 12AWG.
It looks like these range from $100-$400. Any specific recommendations? I don't really think I need one with a sub-woofer. Do I mount the sound bar near my TV or over/behind my bed or?
Sound bar goes directly under the TV. You'll be able to hear it fine from the bed. Go to a store and listen to them to pick out one. I like the Boston Acoustics products, you can read threads about these products in the "Speakers -> Soundbars" forum above...
