There are a few more pieces of advice that I would add - don't feel pressured to change the way you study. I'm about to graduate from law school and for the last three years I've always felt that I should outline and that somehow I was a slacker for not outlining. But that's just not the way I learn so I never outline. If you find it doesn't help you, don't outline just because everyone else does. I briefed for a while but it didn't help so I started just taking notes in the book. Some classes I'd take notes on the reading before class, others I wouldn't. Just depened on the class.
I also recommend not taking a computer to school. I know that first year everyone does, but it is so easy to get distracted. you think you're paying attention when you're really not. Also, you tend to take down anything the prof says without thinking. It's better for me to take hand notes because I'm forced to pay attention and I have to think about what I'm writing. Again, that's a personal preference, but do what feels right for you.
Also, figure out what kind of person you want to be in lawschool. I go to a school where everyone is super helpful and I decided before school that if anyone asked for a copy of my notes or outline I'd be happy to share them. Others may feel differently, but that's just the way I wanted to be.
Definately take time for friends and to go to the gym. Law school takes time, but if you don't have any free time then I think you're doing something wrong.
