I'm trying to figure out the most environmentally friendly and cost effective way to operate my PC. Is turning it completely off when leaving the house a better method than simply using the Energy Star power saving features?

Their is an initial spike as the system turns on, but it is not large enough to warrant leaving the system on.
It is best to turn the system off, and if possible, shut of a power strip or the like to cut off all power to your computer and peripherals, because even when not turned on, computers still draw power. Not a lot, but some. (I've read it characterized something like, "When turned on computers take bites of electricity, when turned off, they nibble.)

your pc might require a bit more energy to power up from a cold start but leaving it on when not in use even with a power saving tool (which by and large turns off only the monitor and harddrive) is very wasteful of energy. The biggest drain on energy in your PC is not the monitor or hard drive it is the internal fans and cooling fins on your processor which are generally on all the time your PC is on

No.
Think about it. Say your computer takes 2 amps. If it took 100 amps for a second when you turned it on, you'd still be better off turning it off if it was for as little as 60 seconds. And you be blowing a lot of fuses. Or, if in power saving mode, say it draws 0.2 amps. The break even time would be less than ten minutes.
The surge when you turn it on is much smaller than 100 amps, of course.
But the Energy Star features work well, and the gain is pretty small. Replace one incandescent bulb in your house with a compact fluorescent and you've done more.

turn it off, then turn off the power bar.
The power saving features are only for very short term, i.e. when you are away for such a short period its not worth turning it off but you want to use less power than leaving the computer and monitor turned on (~15 minutes or so).
Also, you may on be password protected if you leave it turned on. Your parents will be able to find all that porn you've been hiding. ;-)

All tennis video games require potential, speed, qualifications and suggestions. additionally, a strategies that may study the opponent's strategies. Nadal loves clay, this is why he's sturdy with it. yet Federer, he loves grass, and would not rather like clay courts.

I dont think the above means 100 amps. more like watts. huge difference.
