9 people for dinner tomorrow night...?

I am having 9 people over for dinner tomorrow night. I am making a lasagna, fetticcini alfredo, meat, sauasage and a salad. Everything is going to be home made (except the sausage and pasta noodles). Everyone is coming at 6. I always get antsy before a dinner party and start everything way too early and end up serving food that had to be microwaved to re-heat it. Can someone give me a time table to follow that will get everything hot and tasty right at 6?
