First person controller and lighting in maya

When I clicked the Play button, there is a movement of the view in the game panel that goes downwards. I thought my scene could be navigated by the arrow keys or wasd because that is what the tutorials online looks like but it doesn’t work. I am using free version of Unity running on Windows 7 Starter. Pardon my question it is just that the instructions online is easy but I get a different result like this.

and another, I can import anything from Maya except lighting? I just wanted to know maybe it is possible with the new free version of Unity. Thank you for your answers in advance.

as a cheat you can bake light maps into your textures…

I added a rigidbody to my terrain and disabled gravity.
