One of the best pieces of advice I can give you is to not obsess over the college catalog. Freshmen year is about making friends and enjoying your new found freedom.

If you want to learn more the best thing you can do is be a good student. If a topic interests you, stay after class and discuss it with a professor, or visit them at office hours. Opportunities abound for this sort of thing, usually in smaller classes though. I'd recommend getting used to college in your first year and then hitting up professors more when you have found your place at school.
