I think the boundaries you have asked for are reasonable.
I don't think it's necessary to socialize with her, but at the same time your should remember the saying "Keep your friends close and your enemies closer."
if you feel she is a threat, don't stand off. At company functions, introduce yourself and tell her how much you and your husband appreciates her efforts. If you call him at the office and she gets the call, chat for a second or two in a friendly manner and when you leave a message with her say "tell him I love him and to call me when he has a chance."
