Hi
There are lots of campsites depending on style you are looking for, eg pool bar or rustic, I like les vigneaux it's the lower of two sites very rustic, with tree for shade, slack lines and swings, a river running through it and well placed for most activitys
The climbing guidebook is Briancon climbs this is a new version out this April. Needle sport has it in or it is very easy to pick it up locally. There are lots of walking guides out there but I wouldn't bother just pick up a few maps when here, if you get a guide and won't some info on the best areas for kids and yourself then let me know.
For via ferrata I have done most of the one around here with kids of different ages, the one you would be looking at is at puy St Vincent, it starts with rope ladders and bridges never gaining much hight going over a river, there are some vertical rung sections like on a normal via ferrata but you have the option to walk round, still on a cable so easy and hard way, to be fair it's mainly the parents that go the easy way. the best place to hire the kit from is kings in vallouise, you can also pick up a free via Verrata guide there or tourist info, there are defiantly some options after that depending on the size of your kids and how happy you are with the rope side of this? If you would like some photos of that via ferrata so you can get an idea, I think I have some somewhere?
There are also some medieval forts that are great to go and look round.
Hope that helps feel free to ask any other questions
