Well that was easier than I expected.
Orvis has everything in one shot.

Rod:
Now. 4 piece or 6? It is your choice and comes down to space and how much you have.
6 weight or 8 weight? 6 is great for average to smaller fish. 8 is a pretty hefty rod. I use an 8 for salmon and steelhead in fresh water and for 10 to 35 pound fish in saltwater. If you are going to be targeting your typical stream trout you could go with a 4. If you are going to be hitting the blue ribbon streams in NY, go 6. I use hefty lightly as the entire rod will be less than 2oz.
Reel:
Get the same size reel as the weight of the rod.
Line:
Same as reel. Taper, you want a WF taper, floating. That means there is more weight at the front and does not sink.
The Clearwater line has everything you need to get going. This is not junk and by no means is it top shelf. It is quality for the price. It is also above beginner gear because in my experience beginner gear is crap and I have seen too many people give up because they are fighting with their gear or they graduate to the next level quickly and wasted that money.
My fly reel for creek trout doesn't even have a drag. I just let the excess lay on the water for the next cast- my fingers are my drag.
This outfit will get you started in the yard. You will also need waders. Neoprene are warm and durable. But they have a tendency to put downward pressure on your knee caps. These are indispensable if you end up fishing for salmon and steelhead in the fall. The fabric ones are kickazz but offer zero insulation.
Now onto the cheat. Scour planet earth for this book.
Matching the Hatch: A Practical Guide to Imitation of Insects Found on Eastern and Western Trout Waters (by Ernest G. Schwiebert and Jams Prosek)
This book tells you the rivers to fish, what insects are hatching for any given month, the times they hatch, what flies to use and what size. This book will have you catching fish, not practicing casting. Follow that book and pay attention to the hexagena limbata hatch. That is the giant mayfly hatch. The biggest trout in the rivers chase the little guys away to gorge themselves. This is the time to catch that giant trout. Ironically, it's happening, oh maybe, now...May. LOL.
