I am not an expert but I am pretty certain that the answer to that part of the enquiry is yes. As far as I am aware, Greek ID proves that you are a Greek national. Both Greek passports and Greek ID cards would only be issued to somebody who is a Greek national.
The rules on acquiring nationality are described in this document
while this one
is the Greek Code referred to in the following paragraph. I'm not sure if they help?
As far as I can see the rules on acquiring citizenship through birth to parents of non-Greek origin who are long term residents in Greece are still suspended. In fact I think all paths to nationality except by some form of Greek origin are suspended. There is a long discussion in this article
under the section "Challenge to New Greek Citizenship Code 3838/2010". It doesn't look hopeful I'm afraid.
