Just reading through your profile, you seem like an awesome person. I don't know much about transfers, but here are some tips:
-Explain why you didn't apply initially and instead decided to go to CC. This is probably an interesting story and will make you stand out.
-I don't see a list of colleges, but I'm assuming top as in ivy league. As you could probably guess, a lot of the ivy-league fanatics who didn't make it in during high school try again as transfers. You need to make sure the admission officers know that the prestige is not one of the main reasons you want to go there. An easy way I could see you getting the point across is speaking about the research you have done, the research ideas you have, and how your current situation doesn't provide you with enough resources to conduct research. You could also find research that is going on at the institution and mention those, which shows interest.
-Try to contact an admission officer, even if it is initially just for a simple question. Ask the admission office to put you in touch with someone in the research labs or something, and then report back later telling them how well it went and why you are so interested. Just an opportunity to spark some conversation.
Sorry I wasn't much help, but your ECs clearly have focus and your grades/scores are high enough. Best of luck!
