Best method for cleaning a house with fire/smoke damage?

[Billy Daniel]

Hey BP!  I'm currently under contract to purchase a house with fire damage (limited to a couple of bedrooms) and smoke damage throughout.  What tips do you have for this type of property?  What is the best way to clean the smoke?  

I'll be scraping the popcorn ceilings and repriming/painting them.  I'm curious about what to do with the walls and cabinets though.  What materials should I use?
