There is a Rider Waite study group here for you which there are a lot of past threads to delve into - lengthy discussions on the cards, their interaction etc. There is also Thirteens Tarot Basics which are an excellent start. They can be found through the main page of Aeclectic.
Aside from that, today I have just started off a thread called Comparitive Study (in the Using Tarot Cards section) which looks at one card at a time, with contributions from all people and their different decks. The first card is The Lovers and I have entered a post using the Phantasmagoric Theater Tarot. By all means, read the basics around the cards but a good way to start is to get the creative and intuitive juices started by looking into the cards and thinking about what YOU see and feel. There are no completely wrong answers and hopefully, that thread will help you see how other readers interpret the images.
Look forward to hearing your first thoughts from the Rider Waite.
Good luck and best wishes
