I need help with a resume?

I would include EVERY job, internship, and community service project you have participated in. Those are important. As far as the numerous different schools; whoever is reading your resume is not going to know the reason for the high school changes. That's definitely not uncommon. I have attended three different colleges and listed them all on my resume because I took different classes at all of them that still related to the job I was applying for. I included some "awards" from high school such as honor roll, any honor societies you were in, if you were president of any clubs, and things such as dean's list for college
