"i want to install a 24"sharp microwave drawer in a 30" cabinet. Is this possible? what about the extra 3 inches on each side?"
Filler pieces. See the above links provided by buehl.
Can I add an additional question about this 24 inch micro drawer? The instructions say that the plug has to be in the top left corner of the cabinet. Is that they only place that the plug will work? My plug is located in the center of my 27-inch cabinet, but towards the top of the opening. It is recessed into the cabinet so there is not a plug box sticking out into the opening. Moving the plug at this point will be a huge ordeal.

informative but lacking the link info.
