I'd also put in a good word for the Fast Company DVD- and if you follow the link that dat posted previously on this thread, you'll see I've left a post with a link where you can find the DVD at its cheapest.
Good luck honing your skills my friend- as another cardie I can wholeheartedly agree with Lenoir and all the others who've said that it will take years of practice to perfect these skills- A lot of my card work revolves around gambling and gambling themed routines, so if you do have any questions, just pop me a PM and I'll be glad to help
EDIT: On reflection, I don't think the fast company DVDs go into card stacking in any detail, but they're still definitely worth a look- a cheap resource that lists a whole load of gambling related sleights is the book "Card Control" by Arthur Buckley, which you can pick up for a few quid on Amazon.
