The only notifications I ever get are when I have a new message, when I have a new friend request, and when someone messaged me. The one where someone messaged me usually only shows up when I actually check the phone, so I don't actually hear a notification sound when someone messages me, which really defeats the purpose of having facebook chat. What good is it if I keep having to turn the phone back on to see if the other person replied or not. I am not quite sure why it is so difficult for them to get this right. Trillian works well as a chat substitute, however, then FB gets ambitious as well and I get to read the same message on both Trillian and FB. At least Trillain notifies you when someone IM's you without having to turn on the phone. I usually don't leave Trillian running in the background unless I have an active chat going when I leave the house, it's just another battery sucker I'd rather not have running.
