I opened up the first session (Introduction to Derivatives) and I listened to the first 12 and a half minutes but have NO idea what this guy is talking about. I'm feeling pretty dumb now and feel like I need to take easier classes. What are some recommendations? Does he expound, making this all understandable to us of lesser minds, or should I go take a more basic math class?

Hi, I think I struggled a little at first too, but don't worry it will get better, watch the rest of the lesson, then see the notes and try the worked examples, it helped me. I also found this book http://ocw.mit.edu/resources/res-18-001-calculus-online-textbook-spring-2005/ to be quite useful

Use Paul online notes. From some kind of universities in the U.S it helped me a GREAT deal for Cal 1 ( I missed a lot classes on optimization and such and it taught me everything i needed to know for my cal exam ^^) Good luck!

You might want to take a look at: http://www.saylor.org/majors/mathematics/ and go through one or more of the "Foundational" classes (MA001, MA003, MA005). If you're a bit rusty on pre-calculus, brushing up on it first will make this class infinitely easier to follow. That way you can go into this course with that fresh in your mind rather than having to scramble to figure out all the formulas this instructor takes for granted that you know. It'd been decades since I had a mathematics course when I started this one and I "knew I knew" all the stuff the instructor here was assuming I knew ... but I ended up brushing up on the pre-calc and starting over after about a week because having the foundation material solid in my mind beat the heck out of having to look every single little thing up because I "sort of but not really" remembered it. He's an awesome instructor. He just assumes you know pre-calc. Brush up on it and you'll find everything he says makes total sense ... that's what worked for me, at least.
