You can construct your own leaders if you want. Or you can get some tapered leaders locally from Orvis, Bass Pro, Cabelas. Then just get some tippet to match the small end of the taper to keep you from changing out leaders often. For the flies, I'll recommend Orvis again. Alex and some of the other guys there actually fish locally and know what works. I will gladly give you some flies that I have tied to get you started as well.
