You don't need to apply for a French transit visa. However when you apply for the visa to Greece you need to enter "France" as member state of first entry in your visa application (column 23.). You will pass immigration at the first port of entry into the Schengen area (Paris) which consists of 25 European countries. Your connecting flight from Paris to Greece will be a Schengen internal flight without governmental immigration controls before take-off in Paris or after landing in Greece..

Not if you are given a Schengen visa. European Union.
