Shore charges $24.95 a month--but you could probably get the core of what you need within a month or two, and for that it's well worth it. I believe there's also a 7-day trial.

Find someone to pair with, particularly someone who's done a bit of TDD before. It'll be a lot quicker to work through.

At some point, as another poster suggested, read some of the debate on TDD. But learn it first, and from those who have succeeded with it in a professional capacity--so you can be better educated about where its value lies. It's a valuable tool, but no tool solves all problems. (While I currently teach/pair with devs on TDD, I spent at least 5 years doing TDD on professional, "real" systems.)
