Sounds like you have made a good start. We read alot of books about having a baby at our house, but really ownership was the biggest thing that worked for us. My twins are very emphatic about it being OUR baby and thier baby brother. When ever they would see babies I would get them pumped about that soon they would have a baby of thier own. They have been amazing, sweet, and gentle. The one thing is to make sure you protect your baby from toddler exuberance without being so overprotective in that you make your daughter feel bad or like she can't play with the baby. I would almost always try suggesting alternative ways for her to interact with baby instead of other methods of correcting behaviour. Also for me I would get her into her own room with a gate because I would not want to deal with her getting woken every time the baby wakes up at night. Having her own space would also be of help.
