Intereting enough, one of the zombies who showed up on my lot pulled out a stereo and all of them started dancing. The zombie fairy looked a little creepy, but that may be worth looking into. Also, the mailbox cheat is awesome. On a side note for the celebrities thing, look in the options menu. You can opt your household out of the celebrity system, which I believe should prevent any new celebs in your house, thus the papparazzi hanging around.
