Also for something online and RWS, there is Joan Bunning's free online tarot course. There is a book that goes with the course but you can do it without the book.
Those two really aren't that different. Personally I don`t like books with "meanings," I like to discover them for myself by study of the symbols and thinking about them. Even the best books can`t tell you things that aren't subjective, and learning Tarot by rote will only result in those kinds of readings. I agree with gregory, take up a good symbols dictionary, and take your time with the journey.
You may want to learn "the craft" but remember that the actual reading is the smallest part of tarot, it is merely the point in which the reader "gets on stage." The true benifit Tarot can give is behind the scenes.
21 Ways is SO much freer than Bunning. It leads you to discover; I find Bunning so proscriptive that it holds you back. This card does not always mean that - there can't really be a rigidly defined meaning for anything - but she asks you to memorise them as if there were.
