In reply to Rick Asher:
Some great suggestions above,
If you haven't got it get the Oisans Nouveau Oisans Sauvage livre est guidebook by Cambon, cover's lots of the routes you're after.
Just a word of warning for the guide the star rating is not about quality but about gear 1 star being fully bolted and 4 star fully trad.
Not really the Écrins but close just above Briançon, check out the Cerces are some amazing rock routes and quiet if you go to the venues with a hour plus walk in.
