I'd like to pick up some points made by other posters on the 1-on-1s. The Diagonal Palm Shift and the SWE Shift are not gambling or card table moves. They could potentially be adapted into a magician's gambling routine, but they were never intended to be used to cheat.
If you actually want to learn to cheat at cards, then there isn't any book or DVD that can teach you. You need to get yourself a speciality, maybe bottom dealing, and then learn a practical version of the auxillary moves you'll need for a bottom deal to work in a real game. So, you'll need a good, natural-looking false shuffle and cut, and some method of nullifying the cut. Maybe you'll also want a cull, or you may choose to cull from the discards. Also, you might want to learn to hold out. Basically, find a process that works for you and practice it until your fingers bleed
However, if you want to perform gambling sleight-of-hand as a magician, then there are a load of good sources.
The Expert at the Card Table, Expert Card Technique, Down Under Deals, Hand Mucking and Gene Maze and the Art of Bottom Dealing would probably be my favourite books for this kind of stuff at the moment.
