Have you been able to get the 'rayexelec' to turn on the LED Power Strip without involving the Arduino? If you have then tell us how you did so, otherwise we need more information about the 'rayexelec'.
Have you been able to get the Arduino to turn on a single LED, perhaps the one on pin 13, when it receives a Tweet? If not then your sketch needs some work and it is pretty hard to read as it stands right now. Go back to your original post and use the 'Modify' option. Highlight the portion of that post that is code and press the 'Code' button (which looks like a # sign).
