I'm getting two bunnies soon. Any Help?

I have convinced my parents to let me get two bunnies since they like to live in pairs. I have two dogs and two cats. We (my sister and I) were going to keep their cage in her room and not let the other animals in. Do you guys on fluther have any other suggestions? Should they be in one cage or two? Should we get a lamp for them? How high should they be?
