I wouldn't worry too much about holding off. The first book at least is very self-contained and reads extremely satisfyingly as a stand alone. The reason everyone is so anxious for the other two is because he did such a good job with the first one and the expectations are therefore high for the last two.
ETA: If you have any friends who are in or will be in Europe any time soon you may be able to pick up book two sooner since it has been released in English over there - my sister picked up one on her way home from Spain last week. Not sure what the status of the English version of book three is but I seem to recall someone in Europe/UK saying they expected it this summer?
