Agree with what others have said. For a DX camera, the 50mm is not going to be very useful for landscapes...you'll want much wider. The 18-55 is an average lens and you should get some decent photos out of it. Another suggestion would be the 10-20mm DX lens, paired with the kit lens. It will let you go much wider and is not that expensive. You might also consider an all-in-one, like the 18-200 or 18-300. That would give you maximum flexibility without the need to change lenses.
