Guadalajara to Mexico City is not an international flight. 

You check out in Mexico City.    You can find kiosks in the terminals. You will give it to the airline there at check-in.

You have to check out in Mexico City. It is not an easy place to fine. Ask at the information desks.

We flew out 3 weeks ago through Mexico City. Checked in at GDL immigration prior to flight.

Immigration form was attached to boarding pass by GDL agent and collected in CDMX.

It depends on the agent at GDL; we have had some tell us to get stamped out at MEX, a few have stamped us out at GDL.  

Immigration counter at MEX is near Hall (gates) K where most international departures are.  Once you are at Hall K, it is not hard to find.  Many info booths at MEX, just ask for "migracion" and they will point you in the right direction.
