What's the point/benefit for a heavyweight gi versus a lightweight one?

I'm gonna be taking Karate again soon, and I was wondering what I needed to do to get a really good workout to go along with my training. I don't mind if it's very intense, since I want to look good too. I'm 6'4, thin (I guess ectomorph?), but I still have some strength to me. Do I want to do cardio, or weightlifting? If I do weightlifting, should I focus on getting bigger? Also, what supplements should I take? And diet? What are some good foods to eat while training? Protein rich? Or fat free and healthy? Help!
