Joshua,
There isn't a good book that offers what you're looking for. Although I'm a huge fan of The Expert at the Card Table, I agree that the book is long on sleights and short on application. My own theory is that the author had little real-world application to draw on, so he concentrated on what he loved best - the physical moves themselves.
To answer your question in a round-about sort of way though, you have to understand the games themselves. Cheating at Gin Rummy isn't the same as cheating at Hold 'Em, and neither of those are the same as cheating at Bridge. You get the idea.
In Gin Rummy, a good player can get by quite nicely just by killing a few cards (holding them on top through the shuffles and then letting the opponent cut them deep into the deck and out of play). That won't work in Bridge, where all 52 cards are dealt out. In Bridge, covert (and illegal) communication between partners is the move that you have to look out for. Everything else is secondary.
In poker, due to the variety of games and formats, there are more ways to cheat than perhaps at any other game, but you still need to get more specific. In lowball, just giving your opponent a single high card will destroy their hand. In Hold 'Em, while there are some exceptions, giving your opponent high cards isn't something you would normally make a habit of. In Hold 'Em, you might rather know a card or cards coming on the flop, turn or river. The possibilities are many and varied.
In short, to understand application for the moves you've spent so much time on, you have to understand the games themselves. I recommend a good book on general card games and their rules. You'd be surprised at how much you could learn just by reading those types of books.
