Start preparing the wall by locating any knobs, outlet covers, light switch faceplates, thermostats and other items along the wall and take them off. Starting with a smooth surface with no obstructions will help the project proceed much more efficiently.  Most accents can simply be unscrewed and lifted off. Be sure to keep track of small pieces like faceplates and separator, and put the screws back where they belong.  Any accents that you’re unable to remove can be covered with painter’s tape later on. Find a place to store nearby furniture, appliances and other belongings until you’ve wrapped up your project. If space is an issue, you can also simply scoot these items away from the wall you'll be painting. Be sure to cover any remaining furniture with a drop cloth or sheet of plastic to keep it protected.  Paint can be virtually impossible to get out of upholstered fabrics, so it's a good idea to safeguard your furniture even if you think it's a safe distance away from the wall. Unplug all electronics and relocate them somewhere where they won't be damaged. Stretch out a canvas drop cloth or plastic tarp that will help catch spills and splatters once you begin working. For maximum protection, the drop cloth should extend all the way to the base of the wall.  Pass up flimsy floor coverings like newsprint or bedsheets. These materials are usually too thin to stop wet paint from soaking through.  There’s no need to cover the entire floor. Just slide the drop cloth along as needed as you make your way from one end of the wall to the other. Wet a clean cloth or sponge with warm water and a mild liquid detergent, then wring out the excess moisture. Run the cloth over the walls from top to bottom to clear away dust and other debris that can interfere with the paint’s ability to set up properly.  Use a light touch—you just want to clean the wall off, not totally soak it. A small amount of diluted TSP (trisodium phosphate) will be useful for removing stuck-on dirt and grime from walls in dirtier areas like the kitchen or basement. Painter’s tape can be used to protect the trim at the top and bottom of the wall and around doorways. It will also come in handy for putting over accents that are a pain to remove, like dimmer switches. Make sure to line up the edges of the tape precisely, or you could end up with a lopsided paint job.  You can pick up painter’s tape from any home improvement store, as well as most major supermarkets and pharmacies. Look for tape in different sizes. This will give you more flexibility over how to apply it and provide more coverage to keep paint from accidentally getting on other parts of the wall.
