what is needed?

So my fiancé and I just found out which rooms we will be staying in once the baby is one. We also just told his parents (I will be 30 weeks tomorrow). We have some basic items already but i wanted to ask what exactly would you consider essentials for a baby who will be sharing a room with mom and dad? I don't think a full crib is necessary at this point until we move into the upstairs apartment where there is more room. We currently stay in the in-law suite downstairs. We have a small living area with a large closet, three stand alone closets directly outside our living room in the laundry area that we also use for clothing. We have our own entrance from the driveway into our bedroom/kitchen. Basically on the left side of the room we have our bed and night stand, three book shelves, and a TV stand with one of our TV's (it is not used often). My fiancé plans on bringing up the bookshelves and the tv and stand into his old bedroom and bringing most of his video game/music things up there also, leaving the area we live in as just a living room with TV, couch, etc and leaving our "bedroom" as it is, only adding the baby. As I was saying on the left side of the room when coming in from our door is the full sized bed, nightstand and following the wall towards the living area are the bookshelves. Directly across from our bed is the refrigerator and stove, sink and SMALL counter soace along with the cabinets. It is basically a galley kitchen.
