Here is an excellent (and CC licenced) book dealing with these issues:

The website is ugly but the PDF is nice. 

I found it quite helpful for figuring out what actions make the
biggest difference. In my case unplugging my computer is no more
trouble than flipping off a light switch, so it is worth doing even
though the energy savings are small. 

I drool at the lightweight/plug computers, but the Sheevaplug (at
least) is known to run hot. See pretty pictures here:
