If you are thinking about spraying, rent a professional machine and spray primer on everything you will be painting. Spray the walls and ceilings and trim with BIN 123 Oil based primer. (yes it costs a little more but will save you in long run). Then go back and spray finish on the ceilings, assuming they will all be white, spraying just onto the top of the walls. After removing all the plastic and masking, you can go back, sand the walls and trim and get started on them with brushes and rollers. Hold off on any caulking or patching until all surfaces are sealed with primer. After caulking and patching, come back and spot prime the patches.
The oil primer will seal everything in well and should not react with any water based popcorn. It will actually help seal in drywall and make for a better finished surface. Your house will be in a fog when you are finished painting so cover everything that is not going to be painted. Wear a respirator and safety glasses.
