On the electrical thing....if you're going to run your house on a generator, you really should have a transfer switch installed. It breaks the connection to the utility and connects the generator to the home's panel. It also has its own individual circuit breakers for safety. Most places require a transfer switch as part of the electrical code if you are going to run home circuits off a generator.
Either directly connect your devices to the generator using extension cords (or surge supressors) or use a transfer switch. Never, ever backfeed a generator into house wiring without one.
