I don't know if anyone else has had trouble finding out what you need to do if you are planning on teaching in another state. This site is the test that Utah uses, but it also lists the requirements for other states' tests and has links to their licensing websites.
I love videos! Even students who do not claim to be "visual learners" enjoy a video because it keeps their attention and helps them remember the information they are viewing. I have used this website multiple times when teaching lessons in various schools and they have always gone over well. Plus, not only is it a great resource, but it is also allowed in internet filters. YouTube, on the other hand, is blocked in the majority of schools.
