A Wicked Pack of Cards has the most comprehensive info on Etteilla the man. Huson's book explains his system and lists his meanings for the pips only, along with the meanings from other sources. Etteilla re-designed and re-ordered the trumps, so Huson completely disregards Etteilla's interpretation of them. Since Etteilla's pip meanings seem to have come from European tradition, and as he was the earliest person to document them, Huson treats his pip interpretations quite seriously. Huson also occasionally marries the Etteilla meanings with the later Waite/GD materials — as with the five of coins meaning "love", but also "poverty".
Huson's work, including Dame Fortune's Wheel Tarot, is only derived from Etteilla's work as far as the pips are concerned. If you want to take in all of Etteilla's system, I'd purchase one of the Etteilla decks and see how you like it. The trumps only bear a passing resemblance to the traditional models, and many have been completely renamed and redesigned. He was attempting to "reconstruct" the supposed "original" tarot which he assumed, wrongly, came from ancient Egypt. Practically nothing was known about the religions of the ancient Egyptians, and so Etteilla's trumps are psuedo-mystical flights of fancy, really.
