You only need your old passport as identification, you make the appointment and pay the renewal at the time of having the appointment.
If your passport is in good condition, it does not have any observations and you took it out in 2011, you only need to present the expired passport on the day of your appointment. Although, it is always advisable to go with the original birth certificate and other identifications for any questions. If you are going to obtain a consular license, also bring proof of address in your name.
