In reply to it624:
I recommend the following routes:
The first two are fairly exposed but easy ridge traverses, and the second two are technically harder but well protected rock routes. I went with a friend as our first trip to the Alps last year and really enjoyed all of them. There are a few others we did, but those are the standouts. Apart from Cineastes they all felt very remote, we never saw anyone else on the routes. Also make sure you try some of the Ailefroide multipitch sport, it's very good.
In terms of guidebooks, we had the "Mountaineering in the Ecrins Massif: Classic Snow, Rock & Mixed Climbs" book by Chevaillot. It had some good routes in it, but apart from the Barre the snow conditions weren't good enough to attempt any of the other routes when we were there (September), we ended up just doing rock routes. Camp to Camp was detailed enough for all the routes we did, however I had a look through the Gambon and Constant guidebooks recommended above when in huts, and they seemed really good.
Also, when we were there the whole Pelvoux valley (used to access the Ailefroide, Pic sans Nom, and Pelvoux mountains) and the Sele/Pelvoux huts were closed due to a large rockfall, preventing us from doing any of those routes. It may be worth checking if they have reopened this season before you make any plans to attempt them.
