Beans,Soy, and dishes

Question

Rabbi, This is a wonderful service to all of us trying to make our homes Kosher for Passover. I have looked at your list and reviewed many of the Q and A's . I would like clarification on three items. Let me preface by saying that I am an Ashkenazi (sp?)Jew. 1. Do I need to change my dishes, pots, pans, etc. for Passover? I have been doing so for over twenty years, but one of your answers seemed to suggest that this was not necessary. 2. Goya Kidney and Black Beans- are they ok for Ashkenazi Jews? 3. White Wave Silk Soy milk/non diary creamer- my husband only drinks soy milk instead of regular milk. In prior years during Passover he does not. Can he do so? Thank you again. Rochelle Kaplan
