Have you read the follower tutorial by ZZJay, you can change the weight on the traits tab, if you want to change face morphs you will need to create a new female headpart in the CK and then assign it to them on their character generations tab in the box at the bottom right. I would recommend Jay's tutorial. On the custom combat style. I recommend playing around with them. Make a custom combat style by selecting a vanilla one, duplicate, rename and then set the values you want. Same with the class. I made mine using a lot of trial and error.
