Yes, if there was a fire in a block, it means it was Yashur. Or Gur/Alex. As for choosing a target for execution, it's not that simple. There's no evidence against the two remaining mafia members, and you can't execute the widow on the first try. In any case, you have to guess and remove evidence, or immunize/disarm the widow at night, or identify the mafia members based on the voting in the first day. The main goal is to reduce the number of kills at night, but I don't know what would be the best approach.
