Ditto on what DAR said,
Getting proper training is a must, don't faff around trying to teach yourself, that's is a recipe for an expensive mistake.
Suggested reading:
The Compleat Taildragger Pilot. By Harvey S. Plourde
Some of this guys books/vids are quite good also
Tailwheel Training :: Rich Stowell's Aviation Learning Center
Edit: If you do get Harveys book pay particular attention to what he calls the "Jounce"
Also Conventional Gear/ Flying a Taildragger by David Robson is worth a read
