Can I seal the inside surface of an exterior brick wall in my house without trapping moisture in the brick or in the insulation?

I own a 1920s brick house in philly w/ some fire damage. The sellers didn't disclose the damage, so I didn't learn of it until the dog days of summer when the place started to stink of smoke. The fire started in the first floor kitchen and smoked the two rooms immediately above it. I tore down most of the plaster and lath in the two rooms and sealed the joists and studs with bin shellac.
How do I treat the exterior brick wall? The brick is blackened and has a faint char smell. A local restoration contractor said he would paint over the brick, frame out and insulate the walls, and omit a vapor a barrier on the warm side of the wall. That way, the paint would double as a vapor barrier. I'm worried condensation would collect against the painted brick during the winter and grow mold. Is this a valid concern? Instead, could I leave the brick untouched, and try sealing the odor by shellac'in the drywall? That way, the vapor barrier would be on the correct side of the insulation and any odor would be trapped within the wall cavity. OR, should I just pay to have the brick soda-blasted?
Just FYI, I sent the sellers a demand letter and am waiting their response before taking them to small claims court.
