Empow,
I have never seen these two problems, but, with two game breaking bugs, it sounds as though your current game file is corrupted.
I can see why you want to save the game though. I can't promise it will solve anything, but, you could try a factory reset. Or, you could try going into edit town and evicting your family then return them to the same house. (Did you say in your other post that you have already tried this? sorry, I can't remember.) If neither of these work, then, I think you might be left with moving them to the bin, starting a new game in the same town and then placing the family back into the same lot, but, this is going to rather mess up your legacy. Sorry I can't be more helpful. Good luck.
