I am not sure what to do with DS. He will share a room with DD after our next baby is born; he'll be 16m when the baby arrives and about 19m when I'm ready to move the baby out of my room. DS has to be moved into DDs room for me to get the baby out of my room.
My quandary is that I don't know if I should move him into her room in a crib or move him into a twin bed like she has.
My worry is that he would be like a fish in a barrel and if she threw toys in 'to' him he could be hurt or if she climbed into the crib with him he could be hurt. She is pretty rough with him and while we are working on teaching her it's still a fact that she's rough even with her love.

I agree, keep him in the crib. My oldest was 20 months when she switched and she is on the mature side. DS was 2.5 and I think still too early. Maybe get a video monitor?
I think your DD will be fine; 8 months is a lot of maturation at that age.
I also would consider moving them together before the baby comes so they can get used to the arrangement and you can work out the kinks before you are exhausted and getting up with the baby.
Good luck!
