Now unlike any of the previous queens, Eleanor has a wealth of books written about her. For the others it is largely a matter of gathering tit-bits from lots of places - for Eleanor you are spoiled for choice.
For me, the best work on Eleanor is by Ralph Turner Eleanor of Aquitaine. It's not enormously engaging, but it is packed with detail and the best single volume on her that you will find.
From a French perspective, there is the translation of Jean Flori's Eleanor of Aquitaine: Queen and Rebel. I found it to be not as reliable as the Turner, but it's always useful to get multiple perspectives.
If you're looking for something a little less academic and easier to read, then I would recommend Helen Castor's chapters on her in She-Wolves: The Women Who Ruled England Before Elizabeth and Alison Weir's Eleanor of Aquitaine: By the Wrath of God, Queen of England. You won't get the detail or sober analysis of Turner here, but these are far more engaging.
In terms of primary source material, you need to read the chronicles of Suger of St Denis, John of Salisbury, William of Newburgh, Richard of Devizes and Roger of Howden
