A lot of writers have their own style. So I think it'd really be better to pick up some books on screenplay writing FIRST. If you're really serious about it, you should be willing to spare $15-20 to pick up a valuable book. I have 4 books I've bought for TV screenplay writing. Tremendous help. I'm not sure what's good for movies, but if you're interested in TV writing i can suggest some.

Basically it outlines the basic requirements for how to structure the screenplay. Then look at MORE THAN ONE different screenplay. Get a feel for how people are writing it, then you can develop into what works best for you and go that way.
