If you want to get some climbing guide in France don't go to the FNAC this is a really big store and you might be find nothing about climbing. The best it's to go at the bottom of the crags and ask the locals climbers they will help you. Generraly you can find the climbing book of the local area where you are in the closest bar or "tabac presse". I never climb near Toulouse I am from the french Alps. But if I have one advice to give you it's to go to the Gorge du Tarn this is a awesomeeeeeeeeeeeeeeee spot with a tone of routes, all level, up to 200m, always bolted pretty well, after your climb you can enjoy a beer in the river "Le Tarn". A 70m rope and quick draws are enough. I think it's like 3h drive from Toulouse.
Oterhwise you are speaking about going near Nimes, you can go to a nice spot called Russan (too hot in summer) there are a tones of routes too. But one advice to the spot near Nimes WATCH OUT your car leave nothing in it, the best is too open the doors and the trunk, by this way they can see there is nothing in it, they don't still the car but the stuff inside. But in "Le Tarn" this is ok but be carrefull in France this is really to still in the car, not by the climbers but by the others people.
Otherwise man you can go to "les Pyrénées" a mountain range between France and Spain, Alpin stuff, long routes, trad, sport,.... I think 2h from Toulouse. But my advice is to go to "Le Tarn" this is a really major spot in France and it's beautiful too.
