Train-Tram route in Paris from CDG Airport?

I've been to Paris twice and both times I used my train ticket to my final destination..which was in zone 1 (Anvers stop). I think your train ticket will be good to your last stop, but I think it would be easiest to ask the ticket agent at CDG to be sure. I also bought a Navigo p at the same time. I did get a good street map and metro map as it is sometimes hard to figure out where you will pop out of the ground.
