Well, with only having 35 credits at the end of this coming fall semester, I'd say you have very little chances of getting in for the upcoming cycle. The earliest you should apply would for the Fall '09 cycle (meaning you'd start the applications process a little less than a year from now). That gives you time to finish more pre-reqs and then maybe get some experience to, if you don't have much.
I'm not sure when you're looking to apply, and I guess it's possible that you could get in for Fall 2008, but you would have to have amazing stats, and a lot of experience, because I would imagine most admissions committees would stray way from someone who only about 35 credits done. Means you still have around 30 credits to do, which is tough for spring and summer.
But like I said, in the meantime keep that GPA high, high, high up. Don't get lazy, and get some experience, whether it's a job or volunteering. Experience always looks good on your app.
