Here's what I think:
1) Easier said than done, but try to calm down. A week may seem like an eternity...but those seven days will pass by rather quickly.
2) If you already KNOW that she's not crazy about you and your daughter....why are you so worried about her opinion now? If a couple years of marriage didn't change her opinion....don't expect only one week to change her.
3) She doesn't live with you permanently. The important thing is that your husband loves you. So be as nice as possible to her....so that you don't strain your relationship with your husband. She is his mother after all.
4) Pray...and ask Allah for help and patience. And this may sound like paranoia to some....but I think it's generally good to recite the 3 Quls and Ayatul Kursi for protection from Allah....on a daily basis. And especially so if you already know that someone (like your MIL in this case) doesn't like you....or envies you.....or is not well-wisher. Pray to Allah.
5) Sit down with your husband and PLAN out the week. A friend of mind was also dreading a visit from her MIL....and she planned things out with her husband. Plan out what places you will visit.......that way you won't be stuck in the apartment with MIL all day. When you all go out as a family...your MIL will be more likely to behave in a public setting especially around your husband (I'm hoping).
6) Don't go into a cooking frenzy......because there will be some days that you will eat outside. Ask your husband what kinds of dishes his parents like......what things you should get....talk to him about it.
^Buy some items for chai.....like cookies, pastries or a cake from the bakery that you can cut in slices, some mithai and nimko from the local desi store. Have a variety of beverages available...tea/coffee, juice, soda, etc.
^ Don't serve everything in one day....vary it a bit/spread it out. You can make shami kababs and samosay in advance and freeze them......and fry them when needed for chai or as an accompaniment to a meal.
^As for what to cook.......try to balance it out. Have a rice dish (pulao, biryani, etc). A meat dish....(chicken karahi and a mutton korma).....and a vegetable dish like..(palak or saag or eggplant, etc). You can add kababs. A salad, raita, and chutneys. Rotis (you can buy them frozen from the store so they just need heating) as opposed to making them. For desert...make whatever you feel comfortable with....(halwa, kheer, ras malai, etc). You can even buy frozen desi deserts from the store. Buy some ice cream.....and serve it during one of the days of the week. ****Talk to your husband about the menu and ask him for suggestions about what to buy and cook.
7) If your MIL is into movies/dramas/certain magazines......then get them for her....so that they'll keep her occupied for some time while you're busy with chores and taking care of your daughter.
