You could have had a 0.0 in junior high, and if they still passed you to high school, you'd be just fine. Freshmen year, the reason why you want to do well (looks like you are), is to start off with a good class rank.
Oh, let me give you some really good advice. Listen. Do not start thinking about universities now, and do not think about what will help you get in. Do what you want to do, as long as you do SOMETHING. Some colleges don't even look at freshmen year of high school (I believe that Princeton and UMich don't, for example), and others don't put that much weight on it. Sophomore year matters somewhat. Junior year, take the hardest courseload you can ever possibly think of ever taking (choose interesting classes!). You will be set. Just don't start thinking about colleges yet; don't be that guy. High school will probably change most of what you think of all academic subjects and universities. Have fun!
EDIT: Also, don't worry about what others are getting right now. I've seen people be on track to being valedictorian, until they just crashed junior year and couldn't take it anymore.
