Your best bet is to get a good book or video. The Casting videos will drastically cut your learning curve. A local fly shop can be a big help. If you buy the fly line from them they will usually set up your reel for you. You will need a Weight Forward, tapered, floating line. Scientific Anglers, Rio, and Cortland all make good lines. Don't buy the cheapest line. A good line will be in the $60 range. You need backing, leaders and flies.
