Yes, your sister can petition for everyone. I don't know how long it is going to take for either you or your parents. But you will have to look at the USDOS Visa Bulletin from time to time to see where your parents and you are (will be) in the process. The link there is http://www.travel.state.gov/visa/bulletin/bulletin_5452.html. It is pretty self-explanatory. You are looking at about 10 years before you can apply for your green card assuming it is filed in the next few weeks. Your parents will get theirs sooner. Good luck!

Yes, she can petition for you but most likely it will take more than 10 years before there's a visa available for you. If you are single probably what you want to do also is that your parents petition for you as soon as they become residents, and that visa is around 5 years.
