After many months of waiting for somebody else to do it (what can i say, I’m lazy), and with the dumb luck of finding most of the sounds i needed hidden inside the MC360 skin for XBMC, I created an xbox 360 SoundSet for Adium. It is still pending authorization before it gets posted to the main site, but it is available for download here:
Its pretty slick, I love it so far as my personal set, and there are a few sounds (the sounds made when the blades switch on the home screen, for example) that are there but are unused, if anybody comes up with some cool uses for them 
Hope anybody who follows my tiny feed here enjoys them
