Physics Formulas

I haven't taken physics yet and I am feeling overwhelmed trying to teach myself all these topics... What formulas should I solicit to memory?? So far I have been using the Princeton Review book to study for the physics section and it's really helpful in teaching me the basics. I also read on here that people use Chad's videos on coursesaver....is it worth spending the money on this additional source?
