Get an unbeatable entry level, Nikon D3100, kit lens 18-55mm, by "telephoto" in your post I bet you meant telescopic, aka zoom lens. Get one more 35 1.8 dx af-s prime lens for the "standard" (50mm in full frame terms cuz your cam is an APS-C).
Shoot that until it hurts, until you learn the light. Or you can study it on wiki whatnot. But shoot that until you can shoot with your eyes. And then we'll welcome you to the bankruptcy of buying more gears.
My advice, Be a Man. Haul a dinky light plastic DSLR and 2 lenses for now and don't settle for the mini's. You'll thank me when it's too dark for that that shot with a smaller sensor. The NEX with the same size sensor though, is fine. But if you learn to shoot with the optical VF first, you'll be much better. You'll notice the shutter speed and aperture better.
Come back when you're broke.
