Thanks, petey_c for your insight.
So since there's no AC in the bedroom (it's central AC for the house) I will need a 20 amp (bathroom) and 15 amp(lights and receptacles) circuit for each bedroom. So the total for the two bedrooms will be 4 new circuits, if I understand you correctly. A 40 amp feed to a 100 amp subpanel box seems to be more than adequate.
Realistically yes, but you really should have a professional come out and look at it. If you are not happy with the first guy that came to look at your house, you should call someone else and see what they say. If more than 3 people say the same thing, then chances are they see something that we cannot see here. I do hope you get this worked out, but you should really consult a professional.
