Take all original documents, including your birth certificate. Also, depending on the date that your sister filed the I-130 for you, you might need to take documents to show that you were physically present on December 21, 2000. If you don't have proof of that particular date, then take documents showing that you were physically present at some point shortly before that date, and then at some point shortly after that date.
I suggest that you consult with an immigration attorney about your case, before the interview.
