Finally! This was never clear to me until I got a Nexus One and realized that the contacts on the GV app (which are linked to my google apps account) are different from the contacts on the GV website (which are linked to my google account)... At least it looks like I'll now be able to transfer my GV number to the google apps account.
Now I just want to be able to access my Chrome bookmarks from the Android browser and I'll be set.
