My 2 cents... you need a wiring channel from the television to the component cabinet rather than wiring. Wiring between the television and components can, and does, change fairly regularly. Currently, HDMI is doing a bang up job of staying relevant, but that could change fairly fast as well as the equipment you are using.

As for wired vs. wireless speakers, I prefer wired speakers, but if you are enjoying wireless then don't spend the money on wired speakers.

If you want to break into the hi-fi audiophile stuff (which I would discourage) I would recommend headphones at this point. It is just soo much cheaper to get high quality sound on headphones than it is out of a speaker system. I have a fairly nice system and rarely bother with it, I just grab some headphones instead. One day soon I will get around to selling my amps and speakers.
