Your goals probably aren't realistic, you're 15, you're going to grow, eat healthy meals 5-6 times a day, train hard and smart and see what weight class you end up in. At your age weight I don't think it's a good idea to try and limit growth.
As far as what to eat, and how to train, read the stickies in the diet & training sections.
Basic list of foods should be:
Milk
chicken
steak
fish
brown rice
sweet potatoes
red skin potatoes
oatmeal
eggs & egg whites
cottage cheese
Whole Grain/Whole wheat breads
almonds, walnuts, etc
vegetables (salad, carrots, broccoli, etc)
fruit
combine these items into meals, generally taking in protein, carbs and fat each meal
As far as training, I don't know what you do for wrestling. If you train 2-3 times a week for wrestling, you may only want to lift ~2 times a week. In that case you could do full body workouts 2 times a week, or one day upper and another day lower body. Make sure you balance your training with lower and upper body exercises, stay off machines for the most part, and perform exercises correctly, generally no partial reps. Also, generally try to keep each workout around ~15 sets or under, no 25+ set marathon sessions.
