The hair and clothing that I posted already is all that comes with the stuff pack. It has very little in the way of home furnishings, too. A few light fixtures, dining table and chairs, some outdoor things for children (sand box, spring rider, etc.). The rest of it is all the replacement buildings for around town. There's a new gym, cafe, library, laundromat, grocer, small park, and school. From what I can tell so far, the new community lots are smaller than their original counterparts, so it shouldn't be a problem placing them. Also, there are no new residential lots at all.
Here are a couple of pictures of the Scrumptious Nibbles Cafe in place of Hogan's Diner.
