Paris' Gare de l'Est is the station you'll arrive in if you've taken the train from Luxembourg, and other central-eastern parts of Europe like Frankfurt, Germany and the Gare de l'Est station is also the train station you would depart from to head in that direction.
Gare de l'Est is just one of the six major train stations in Paris. It's not a particularly huge train station, but it has everything you need. The station is reasonably clean, and easy to navigate. You'll find some magazine stands and little bistro's where you can grab a bite to eat, and the washrooms are easily accessible (though they are pay per use).
Gare de l'Est also has a a currency exchange and is easily connected to the rest of Paris via the metro system. Beware people trying to sell you passes so that you don't have to stand in line for the Metro ticket machines - There's no way of knowing if the ticket actually works.
You'll probably run into several other backpackers and budget travellers in the station too, as with most train stations. Overall, this is one of Paris' better train station though one of the older and smaller of the Paris train stations.
