If I understand your question correctly
You went to get the passport stamp with your courtesy copy. I haven\'t received my plastic card yet, but I did my passport stamp with the courtesy copy, this is OK as far as I can say, and nothing else needs to be done but wait for the card. If the card takes an excessive amount of time you may consider talking to an IIO or sending form G-731 ( I hope I got the number right) for your service center, asking for your card production status.
