I would keep the changing table in the baby room. Start changing her in the bathroom (unless its poo) and let her sit on the potty for a minute or two with a nakie butt. She may surprise you and train herself.
Being in your 9th month of pregnancy I would say bring her to the changing table for a poo diaper and change it very fast and quickly leave the room so she doesn't associate it as "her room" anymore. Keep the door closed and don't let her play in there.
As for the crib issue... eliminate it as a choice. Tell her its time for bed in your own room in your new bed. thats it no negotiating.
