Working on your calves will help with your running - it'll also help strengthen your tibias. Shoes are extremely important - often shin splints, foot problems, ankle, knee, and back pain can all be alleviated by proper footwear or an insert. Also, if you are going to be running on a track for school, be sure to run on a track regularly to get used to the very slight give of a track as opposed to pavement.
When you wish upon a falling star, your dreams can come true. Unless it's really a meteor hurtling to the Earth which will destroy all life. Then you're pretty much hosed no matter what you wish for. Unless it's death by meteorite.
