power down mode and port pins
no matter what, the LED is going to be using current if it's on, no way around that. Using 2 pin won't change anything at all. The only option not mentioned is to run the LED at...

avrdude on 64-bit XP
Why don't you try it and let us know? It works in 64-bit Vista with one change made by MadWizard.

8-bit music?
yeah, there are a lot of headphones ranging from 32 ohm to 600 ohm, I was just saying that the standard, cheap headphones are 16 ohm.

8-bit music?
Most headphones are 16 ohm nominal impedance, so they need a halfway decent amount of current.

PIN change interrupt
You missed a few steps there. Declare a global variable volatile, then read the pins into that variable BEFORE the cli() somewhere, I would do it before the while loop. Then you...

[TUT] [C] Newbie's Guide to AVR Timers
Shouldn't it be TIMSK1 instead of just TIMSK?

If you're using GCC, check out this thread, especially Part 5: Otherwise, tell us what you're using.
