You can use the InterRail with any train in France (or Europe) run by state railways except the Eurostar (from Paris to London). If you're going to use the TGV you have to know that reservations are mandatory so you'll have to take care of that before getting into a TGV.
When you'll receive your InterRail it will contain some papers that tell you what train require reservations, maps and other useful informations so you don't have to worry about anything.
RATP is not supported because it's just for Paris metropolitan area. As long as you travel between two cities (towns, villages, etc.) and the train is from SNCF (or any other state railways company in Europe) you can use your Interrail pass.
And yes, www.bahn.de is the best when it comes to information about trains in Europe.
I have found free rooms in all cities I've been to but it takes so little to book a room that I highly recommend doing it because you don't want to lose precious time searching for hotels.

Train tickets that are booked in advance are usually made up of two parts: the ticket itself and a seat reservation. A railpass will cover the 'ticket' part of all your journeys, but does not cover any reservations.
Most regional trains do not require reservations, and so you can travel on these with just the railpass. But if you are planning to travel long distances, it's likely that you will always be travelling on trains where reservations are compulsory.
http://reiseauskunft.bahn.de/bin/query.exe/en is an English version of the bahn.de timetable search tool. You can use this to see if your trains require reservations:
However you should be careful when using bahn.de because the data is not always fully up-to-date for trains outside of Germany.
I'm not 100% sure, but I don't think it is possible to purchase reservations directly from http://voyages-sncf.com. This is because that site is designed for French people, and the railpass rules are that you can't use a pass for the country you are resident in. You can definitely purchase the reservations from any one of these SNCF subsidiary websites:
Note that the prices on these different websites will not necessarily be the same, because each site sets its own exchange rates. SNCF has a few other subsidiary websites, including http://tgv-europe.com, but I don't think it's possible to book reservations on these sites.
You can also purchase reservations from Loco2.com, which I run:
Our site has a connection to the Rail Europe booking system. The prices for reservations on our site will be the same as at raileurope.co.uk (but we are a completely independent company, and we take international credit cards).
Before you actually book the railpass or any reservations, you should consider the following:
It can often be cheaper to buy point-to-point tickets instead of a railpass. See http://loco2.com/engine-room-forum/railpasses/railpass-or-point-to-point. In recent years railpasses have become less and less cost effective, as the compulsory reservation fees for high-speed trains have increased
The official Interrail website at http://www.interrailnet.com offers better prices than Rail Europe for the passes themselves and also includes lots of helpful info about reservations
If you are not a European citizen, you will need a Eurail pass, not an Interrail pass - http://www.eurail.com/ (this is the same company as the official Interrail website above)
Hopefully it will soon be unnecessary to do so much manual research to work out the costs/booking options, but this will require the rail companies to be more open with their data (for example so that the timetable data accessible via bahn.de can be combined with the booking functionality for actually purchasing the reservations).
