Since organized communities are usually more enjoyable, you should take your time to read the forum rules to save yourself some trouble and help keep the forums clean :-)
I'm pretty sure that adding achievements to a game that wasn't set up for achievements in the first place is impossible. Since Halo 2 Vista was reworked and designed for the PC, Bungie, (or whoever worked on it), had the ability to throw in a few achievements.
I've never played Halo 2 Vista or any other Xbox game for PC, but I would imagine that as long as your signed in to your gamertag on Xbox.com that they would go towards your gamerscore. Like I said, I've never played an Xbox PC game, but I would imagine that you would earn gamerpoints by unlocking achievements.
