adding materials problem

hello everyone, i have a lot of questions but i’m going to ask the most important…
how can i import the materials that this page contains?
i know that i have to go to the materials editor then right click on scene material and then import a new material but when i import that new material, something like a kind of grass or concrete or wood, the preview sphere shows me the gray diffuse color and not the marerial that i import previusly…then i apply the material to the object and when i render it nothing happends =/
