Welcome back. Ditto what the guy said about the huge changes in the sport in the last 10 years. I recently upgraded my 15-year old equipment, and what a difference!
I've tried out several of the bow hunting magazines, and while they're entertaining, I didn't get much out of them. They're half-advertising at any rate. The websites mentioned above (and this one!) are a great start. Also, any of the books from the Eberharts (father and son that wrote some excellent books on bow tactics) are a must IMO. Some great lessons in there to shorten the learning curve and avoid some bad habits.
