Household lighting project

Okie dokie, so next project! woot, got most my sensors working now just to do the light stuff

I'd like to get 12 BlinkM's or RGB LED's and actually work them into my living room.... Goal 12 x RGB LED, Wi Chuck to control color/brightness, Arduino, i'm guessing for control + wireless shield for Wi chuck?

So materials

Arduino 12x RGB LED Wi-chuck Wireless shield?? Guessing Xbee or bluetooth shield, how does Wi chuck work?

and last is how to power all these darn things... i'd like to run them directly into a single outlet, or direct into the household power...

Goal is to have RGB LED's color controlled, and all built into the house to reduce power consumption.

Thoughts Ideas???
