Beadboard Bathroom

We are thinking about installing beadboard in our bathroom. Most of the pictures I've seen have a large baseboard, looks to be about 6" or so with a 1/4 round on the floor. I was wondering about how to place the beadboard next to the door frame moulding. Should it just butt up to it then add a small bead of caulk? Also, how about where it meets the ceiling? Should it butt right up to the ceiling and some type of moulding placed around it?
