Home Wiring?

The only weakness in my currently killer system is in the power section. Right now I'm still running it off my main house box with all the components on the same line out of the same outlet. I know - not a good idea. So I'm here to ask about how I should go about putting in a dedicated line. What do I need? What audiophile level parts should I get? Do I need an electrician? Can I put in another box? Does anything I get have to run off the incoming power from the power company?

I really have no clue about this stuff. I was looking over at Audioexcellence for outlets (the Oyaides look nice) and Acrolink in-wall wires. Any other suggestions?

Thanks.
