You don't need your birth certificate or social security card. They are easy to replace. A birth certificate is a public record: you can order it from whatever government agency handles vital records in the county of your birth.
Social security card is marginally more difficult, but if you know the number, it is surprisingly easy. Just go down to the nearest social security office with your story, and they'll get it sent to you.
