Don't use power strips in any way unless it's high end. Get everything away from flourescent lights, your phone etc.
Best place to start IMHO is to use a computer that isn't connected to the mains - So a laptop running on battery, using its own internal screen and monitoring with headphones.
In terms of electronic noise, those big power bricks are some of the absolute worst offenders, but they can feel like part of the furniture that you don't think about.
