The format is standard flashcard stuff. Each card has a citation to the relevant CBA section(s) to facilitate an examination of the actual language if needed. I did my best to boil down each section to only the relevant information and to translate from legalese into layman's terms much as possible. Obviously that involves some changes from the source material, but that is why there is a citation to the language itself if anything is unclear.
So, here are links to flashcards on Articles I, II, VII-XII, XXIV, XXV, and XXVII of the CBA. These are the Articles most relevant to player acquisitions and transactions, which is what most people are really interested in. The site, Cram.com, also has a useful app that will allow downloading of these cards to smartphone or tablet for self-quizzing.
Article II--Uniform Player Contract
Article VII--BRI, Salary Cap, Escrow, Luxury Tax, Trade Rules, Exceptions. Team Salary, Extensions
Articles VIII-XII--Rookie Scale, Length of Contracts, NBA Draft, Free Agency, Option Clauses
Article XXIV, XXV, XXVII--No-Trade Clauses and Set-Off For Waived Players
Here is a link to a slightly modified version of the CBA PDF itself, bookmarked by section for easier reference. For convenience, a (non-bookmarked) copy of the NBA Constitution and By-Laws is included as well.

Thanks to Larry Coon and Eric Pincus for helping me to clarify a few issues and discrepancies. And Larry's seminal CBA FAQ was invaluable when struggling to decipher some of the trickier sections. Also, this process was made a lot more enjoyable by the presence of Danny Leroux during all the weekend study sessions.
It should also be noted that if you don't have any familiarity whatsoever with the CBA, this may not be the place to start. In that case, the CBA FAQ should be read so that you have a foundation. The point of this is more to have a method to really memorize the nuances rather than be introduced to the general concepts.
I would greatly appreciate any feedback if anyone comes across errors. Feel free to contact me on Twitter or at email@example.com with any thoughts. And you can catch all of my other work since June of 2013 at Basketball Insiders. Thanks for reading.
May 28, 2014 Update: A previous version of the cards stated that the BAE could not be used if the MLE had already been used. That has been edited to the proper statement, which is that the BAE cannot be used if the MMLE (Taypayer Mid-Level Exception) has already been used. See Article VII Section 6(d).
