I will graduate this coming fall and receive my teaching degree

A love for kids is the first and foremost most important thing to have. You have got that so you are off to a good start. As for worrying with what classes to take, don't worry with that until you get to college. At college you will have an advisor that will help you choose all the classes you need to take to get your degree. It will be good to have the practice at those lesson plans though. Trust me you will be creating more and more and more of those, til you can't stand it. Just follow your passion and don't worry about all the details until you get to college.
