Not sure about poweroff but I use a script I found in the Kindle Dev forum.
Code:
#!/bin/sh
exec shutdown -P now
Device turns off and you a get the boy under tree image with a "Please wait a moment while your Kindle starts up..." message.

Not that I can tell.

Same as you do when you get a brand new Kindle (press power button for a few seconds) and boot time is just as long.

Long term storage, sure. For example, I bought extra Kindles that could be jailbroken for backup purposes that are just sitting in a drawer unused for months on end. Makes sense to turn those off.
Normal usage, just stick to standby.
