I just finished the Arles away a few weeks ago. I relied on the Gronze website (which, as others have said, Chrome will translate for you) and Miam Miam Dodo, which is pretty easy to follow even if you don't speak French. Gronze is great for letting you quickly see the distances between places and what lodging there is - including some which aren't listed in Miam. Miam gives you lots of info about lodging as well as things like grocery stores, restaurants, bakeries, water fountains, etc. It also gives you profiles of trail elevations with better indications of difficulty than Gronze. You can get it as a hard copy or download it to your phone.
The CSJ guide is goodbut you will also need the Miam-Miam-Dodo Guide. This is in French but is very simple and mostly icon driven so I defy anyone tobe incapable of understanding it; it has information for each village and town covering accommodation/cafés/restaurants/shops & supermarkets/buses/trains/potable water........you get the idea and it also has basic maps. I met a guy who was walking the Arles and it was his only guide book.
