Cat-alac,
I can't really speak for the GCBC. I currently fly a 77 Decathlon (150 HP, fixed pitch prop) which is similar, but different. On the subject of your TW endorsement, you'll probably get a wide variety of suggestions. For what it's worth, here are mine...
Before your first instructional flight, I'd get a copy of "The Compleat Taildragger" by Harvey Plourde. I found this book to be most helpful to me. If you read it once before your first lesson you'll find yourself more prepared than most. After your training begins, it becomes a good reference source. You can revisit the chapters of significance and it should support what your instructor is teaching. It's a great book and a great way to build your TW foundation.
Landings... Let's just cut to the chase. You have to be relatively comfortable landing in a crosswind. The utility of your airplane will be significantly reduced if you can't or don't want to land in a crosswind. You and your instructor, toward the end of your training, should find a field that presents a good crosswind and you should practice until you have a certain level of understanding and comfort. I've heard that some instructors will sign students off w/o much, if any crosswind experience. That's really a shame. Of course, your partner may be able to help you out, depending on his/her experience level.
Other than that, have fun. I really enjoy my Decathlon and the challenge it presents.
