Could you add a motion sensor to that flood light? Of course, you wouldn't use a CFL with it then, but it would be on only when really needed.
I'd put everything you don't need on a powerstrip and turn it off when not in use. In our house this is:
RTV corner (37" LCD, DVD, sat, speaker amplifier) - 20-30W in standby,
Desktop computer + 19" LCD monitor + printer - 10-15W when everything is "off",
Stereo - 10W when off, 11-12W when on,
Internet radio receiver - 5W.
I also found that our driveway gate's motor uses 30W just doing nothing (waiting for signal to open), so I turn its circuit breaker on only when the car is in use.
So, once you've checked everything that is plugged in, you should look for
phantom loads that go straight from the circuit breakers.
