Over the last few years, one of the greatest tools that I have found for learning NLP is the series of card decks from Salad Ltd. The founder of Salad, Jamie Smart, is not the first to put out cards which practice language patterns, but he has taken the idea much further than anyone else, and he now offers six different sets of cards.
At this very moment (early-December 2010), they are offering a very good value offer on all six packs. I have no connection with the company at all, but I have a lot of respect for the work that Jamie Smart has done in putting together this amazing resource.
If you are serious about practicing NLP language patterns until they are truly "in the muscle" or "wired in" or whatever your favourite expression for mastery is, then I highly recommend these cards, especially the sets:
