Make sure you research your tailwheel instructor thoroughly. There are instructors out there who expect to teach "tailwheel conversions" having just done a few hours on a tailwheel course themselves.
You need an instructor who regularly flies tailwheel aircraft and understands what is going on. Also one who can give you the proper briefings for the type you are flying.
Now let me agree with the others that "The Compleat Taildragger" is probably the best book on the subject (note the spelling of Complete). It costs about twenty pounds. A less expensive, but fun book, is "Taming the Taildragger" which should get you in the mood.
Good luck and enjoy learning the skills.
