As you get back into tying, be sure to check out FAOL's fly tying section. It is a treasure house! The highlight is the fly tying instruction series done by the late, and deeply missed, Al Campbell. He takes you through the learning process in a great way that builds your skills as you move through tying a series of flies that teach new skills while building on what you have learned. It is a remarkable resource.
Al was a bit handicapped in this by limitations on the photos he could use. Another great guy and great tyer is Charlie Craven. His site doesn't teach a tying course like Al's did, but it makes great use of photos and detailed instructions to guide you through the steps. http://www.charliesflyboxinc.com/flybox/index.cfm
FWIW, I started tying using Al's course here and a couple of books. Then I signed up for my local fly shop's beginner lessons. I felt that I got far more about of the local lessons than my classmates did because I had already reached a point where I knew where I was having problems and what my questions were. But, if you are already signed up, I'd say go for it now. Tie for a few months, then sign up for the local shop's intermediate classes.
Also, search the Net to see if there are any fly tying shows near you as you go along. You can get an incredible amount of instruction on the Net, but there is nothing as good as sitting down to watch and question a skilled tyer in person. When I bought my first rotary vise I went to a tying show and as the crowds died down in the afternoon, sat at the tables where the tyers were using my vise. I told them that I was new to that vise and rotary tying and asked if they could show me some tricks to getting the most of it. I learned an incredible amount that afternoon.
