Echo those thoughts.........take a class. Not only will you learn, but you will also have a load of fun. I took a class at a local flyshop in the evening. I got the basics, shared lots of stories, got some fishing advice and met some nice people.
If your interest in fly tying holds (and I'm sure it will), I would also suggest "The Fly Tyer's Benchside Reference". It's expensive, but it has absolutely everything you'll need to reference and is loaded with step by step instructions and colored photos. Great book!!!
Enjoy.....you will not regret getting started.
