Farms big 100 - who sees ads

I'm setting up my ads, and read through these forums. I read that the theme pack was setup to handle the ads, but as I look into the themes, I see that they are setup with different wsa names, like wp_ozh_wsa("336x280-bluebird"), or wp_ozh_wsa("336280nocolor") and so on.

I know these tags were added to make things more simple as far as finding good places within the theme to display ads. I realize one size doesn't necessarily fit all. But I had a few questions:

1. Is there a list somewhere that will give me all the names that were inserted into the themes?
2. Is there a global name I can use since it looks like (at least the themes I have looked at so far) that the names used seem to be pretty theme specific.

Thanks.
