You should etch off any effluence on the surface of the concrete and clean and prep thoroughly before you start. Ask the paint store for a rec to match your situation.
Ditto on spraying the open wood framing in the ceiling. You will need to seal and prime it like any paint job. Then apply two coats. I would use a flat or low sheen paint.
