I don't know the name of the line but when you get to Gare de l'Est don't leave the station, follow the signs to the metro. So you'd be taking escalators down. There are Metro Maps posted everywhere near ticket sales so look for the line that will take you to Gare St Lazare. You've got plenty of time however sometimes it takes a while to get the subway ticket so I would suggest that as soon as you arrive get the ticket first.
you can take the bus 32 at gare de l'est and the bus is going really near Saint Lazare.
