Hello dkg,
For some reason I only noticed you posted further questions.
You can only apply for the Spanish nationality after one year of legal residency in Spain, therefore, you will have to wait until March-April 2014 to be able to file the application at the corresponding Civil Registry ( not the Immigration Office - Oficina de Extranjeros ). Please be aware a nationality application takes on average about one year to be resolved, no matter the Civil Registry.
You can find more information about the requirements and process
here.
Regards,
