Yes, get requirements out of the way. It makes things easier. I came into college undecided with no clue, so I just did all my requirements that weren't filled by APs. Now, I'm in a bit of a mad rush to finish on time, and having all the general stuff taken care of makes things so much easier. Plus, if you're not like me, you might have room left at the end for something random that interests you to make your last semester or year a little less crazy. It's all about learning what interests you anyway.
My first college class was a History of Western Civilization thing. It was taught during my high school day by a teacher from the high school, but they were also employed by the community college as a professor and taught the course to people who wanted a head start with college courses and credit. It was pretty nice coming out of high school with 6 credits (2 semesters) in addition to my AP stuff. Leaves some leeway in college scheduling, since you can afford to take it easy for a semester or two in terms of number of courses you're taking.
