Kim: Welcome to the forum, sorry I didn't see your post sooner!
Edit: I can't help with the local classes, but +1 for what Fred says below. There is a ton of information on this site, spend some time browsing and using the search function, but don't hesitate to ask questions.
You might also want to take a look at the Orvis Learning Center, lots of great information there for beginners. http://howtoflyfish.orvis.com/
Also take a look at the Orvis Fly Fishing Podcasts by tom Rosenbauer, there are very well done with tons of great information. http://orvisffguide.libsyn.com/
Another site that has some great episodes is Ask About Fly Fishing Internet Radio. Take a look at their archives, I think you have to join to listen to archive episodes but it is free for a limited use. http://www.askaboutflyfishing.com/archive.cfm
Also don't forget YouTube, it has hundreds of videos on fly fishing, fly casting, nymphing, etc.
