Well, the false cast isn't really just a method, it's a mainstay of fly casting. The false cast enables you to adjust your distance, it's how you aim your cast, and it can help to dry out your fly if you're using a dry. Beginner or not, you have to master the basic cast if you want to fly fish.
The roll cast is also important, but I'm not going to even try to describe it. It's best for situations where your back-cast area is not clear, and when you have a lot of unfriendly wind.
There are a number of casting videos on YouTube. Do a search on fly casting and watch a few. Some are pretty good, some suck. You can also get books and DVDs from your public library on fly casting, though I have to say that learning to cast from a book like learning to speak Spanish from someone who only speaks in sign language. Stick to DVDs for casting instruction. Sometimes schools, angling clubs, or other organizations have fly casting seminars. My chapter of Trout Unlimited has a couple free seminars each year. Check around your area for opportunities like that -- the best way to learn casting is personal instruction. If you have some extra cash, consider a class.
