First, you cannot file single if you are married. That will definitely create problems.
Second, do not send the originals, only certified copies. Only the person for whom the ITIN is requested needs to provide these documents. Since the passport only has the maiden name, I suggest to have your marriage certificate translated and certified as well, or, maybe even better, get a new passport with the married name and a certified copy of that passport at the same time. The certification needs to be done by the issuing agency (ideally in English, otherwise you need to get that translated).
