Hey there Sarge,
I can help you with the Trim Code. It is made up of the GMH paint code (the first group of numbers) and the GMH Trim Code (the second group).
Check out
http://www.fefcholden.org.au/techinfo/gmhpaintcodes.html which explains many of the paint codes. 200 represents "Huron Green over Ocean Mist Green", which of course corresponds with what you previously wrote.
The GMH Trim code of 708 denotes interior trim to suit a special sedan in "Tasman Green & Egret Ivory". More details about trim numbers can be found at
http://www.fefcholden.org.au/techinfo/fetrims.html. Typically when dealers ordered a piece of trim, they supplied the part number with this suffix, to ensure the right colour arrived. I'm not sure why there are multiple numbers that all seem to correspond to the same colour combination (471 and 708 both mean the same thing), but I presume it was to allow GM-H to identify the material supplier.
I've seen the "AO" suffix plenty of times, but I can't tell you what it means
cheers
