To mute the volume during shutdown you could try this method which works on my G4 tower. I don't have the time to test it on my Intel right now.
Unix has special scripts that get executed during startup and shutdown. As a safeguard the system also looks for custom 'local' scripts named rc.local and rc.shutdown.local in the Unix directory /etc.
In the shutdown script place
osascript -e "set volume with output muted"
In the startup script place
osascript -e "set volume without output muted"
That startup script will restore your volume to what it was before you muted on shutdown, but after the startup chime would have sounded. In other words, this gets you silent startups.
You'll need sudo (admin) privilege to create or alter the files. Search the forums if you don't know what that is.
