My advice 
1) Go to the Thoth Forum of course
2) Read Lon Milo Duquette's book on "Understanding Aleister Crowley's Thoth Tarot"
It does not focus on using the cards for divination, but instead explains the system that Crowley was illustrating in his deck. So if you want to use your own interpretations, then this book may be ideal also. It doesn't really tell you any meanings (except for in a weak little chapter at the very end which is comparable to the LWB) but instead discusses the features that are unique to Crowley or similar decks.
3) Then have a go at Crowley's Book of Thoth which may be found here

3b) if that book excites you, there is heaps more of his stuff online here

4) I found Banzaf's books useful too, and would recommend "The Crowley Tarot" as the better read. "Keywords for the Crowley Tarot" I think is mostly useful as a quick reference, and with the Thoth I never want to refer quickly.
