i have a 3.7 and i was just accepted as a transfer to ILR (i just found out about an hour ago, actually!)
you'll need the grades. I'm currently a freshmen at Onondaga Community College, but with the sheer number of courses i've taken this year (and will be taking throughout the summer) i'll technically be a junior at cornell. If your high school grades are strong, you should be good transfering whenever you want. Make sure you attend transfer day in the fall!! It's a wonderful look into the school, and they do care about your interest in the school.
i interviewed with Mary Van Arsdale, the dirrector of admissions at ILR, and she said that the grades are the most important aspect of the application. It doesnt matter what you've done outside of school, w/o the grades you wont be admitted. Then, other stuff comes into play, she seemed to focus in on the courses i've taken and which of those courses I have enjoyed most.
if you have any more questions, post 'em and we'll try to answer
