to smooth the hills out you can:

apply a smooth modifier, (it may make the mesh VERY heacy though) could you chuck up a wire of the geometry so I can see how heavy it is?

Or you can increase the initial amount of faces in your mesh. Also there is a displacement setting initial samples is the one I am thinking of. Those might give better results..
