Annoying Mother-In-Law

I`m so glad to find this site, because I just got married and I already see trouble with my mother in law ahead. She is incredibly narrow minded and cheap and wants to butt into our life as much as she can. In addition, she is passive aggressive and always talks about how she doesn`t want to butt in at all. Last month she came over our house and spend hours talking about her wonderful children and how lucky anyone who is wither her son should feel to get "such a wonderful boy who is so talented". All of this was to lower my self esteem so her son could have the upper hand. She has also gotten into nagging us about coming to visit even though we just graduated from school and my husband is still looking for a job. She also likes to make snide remarks about my money spending habits and about how I don`t cook. Well, first of all I am the only one in our family working right now, so it is not her business how I spend my money. And secondly, the world it a different place from 1953 or whenever the old hag was young, so I don`t owe it to my husband to cook and clean for him anymore. Right now, I can see that she is still holding back a little because we just got married and she knows her son loves me and doesn`t want to ruin it for us, because he is miserable when I break up with him. But the longer we are together and the more stable our relationship is with my husband the worse she gets and I can see her being a real pain in the ass. My husband yells at her sometimes when she gets out of line, but he gets mad at me if I criticize her and even told me that "You have to be nice to my family and take all their crap", which I think is unfair because oone has a right to tell me what to do and because it shows that he realizes that they dish out crap and still expects me take it. Also, my mother in law wants to move to our city soon(now she is 3.5 hours away, which is not far enough for me). So, I need advice on how to lay down the law with her from the start, so she knows she can`t butt in and that she doesn`t have any say in our family.
PS she already told me that it`s better for me to have kids upto age 26 because later my bones will get old and that I need to fix my teeth otherwise I won`t be successful at my job.
