What products are useful to clean mold in a house?

In Atlanta, Georgia, my fiance's house has been sabotaged by the pouring rain over the summer. Since we haven't been to it since April, it has collected mold everywhere. We are going there this holiday to get it somewhat cleaned and pull out all of his art that wasn't destructed. Does anyone have suggestions on what cleaning products are useful? ie: a mop, broom, rags, chemicals, scrapping materials...
