In reply to Moacs:
The Aiguilles Rouges go all the way (on the Cham side) from Les Houches to Finhaut, so you actually have a lot of choice. And it is max an hour from Les Houches to the Emosson dam, so the travel times are not huge.
I'd be tempted to stay somewhere between Les Praz (at the bottom of the Flegere lift) and Le Buet. You will be at the heart of the Aiguilles Rouges, with easy lift access at Flegere. You will also be well placed for the Le Tour lifts to access the Albert Premiere hut and Aiguille du Tour area on the other side. The trains are excellent so you don't need a car (although Emosson is a bit harder to reach as you have to then use a train+bus to get up to the dam).
Guidebooks is very dependent on what you want to do. The Cham valley guide has very limited Aiguilles Rouges stuff. Piola is excellent (but 2 vols so pricier) but it does cover all the routes and areas - and there are a lot of them. Rockfax is surprisingly good, but is a whole area guide so has an awful lot of high mountain stuff that you want to avoid, so your route choice will be limited. If forced to chose, I would go with Piola as you will be spoiled for choice and can pick and chose whether you want solitude or busier classics.
Hope you have a brilliant time!
