Is Al right? Am I really saving the environment by switching to CF bulbs?

My wife and I, like most folks, have jumped on the compact flourecent bandwagon. In doing some more research, I've come to find out that while, yes, you can save a ton of energy in your home by switching, there is, like most things, more to the story.
The Energy Star folks tell us to leave the bulbs running for at least 15 minutes per use even if I would normally just switch the light off when I was leaving the room. There's mercury in them (yeah, there's mercury in coal, but only half of US electricity generation is coal fired). There are more parts to them requiring more energy to produce them. My house's heater has to work harder to make up for the loss of incandecent bulb heat (inversely of course the AC works less)...
So, what's the deal? Is there definative, accurate, mostly unbiased information that compares the actual and entire environmental impact of the various forms of lighting available, incandecent, flourecent, LED, halogen, big red tallow candles mounted on human skull sconces, etc...?
Please scienticians, male answer syndrome sufferers, environmental wack-os, global warmng deniers of the hive mnd set me on the right path!
