I think when you say ''pos,lookat,up'' you mean you have set your view matrix. Not the world matrix. To set your world matrix you should use functions,

D3DXMatrixRotation
D3DXMatrixTranslation
D3DXMatrixScaling

Those functions set up the world, then you setTransform with the world matrix, and render your mesh. Generally it would look something like this

-Set projection matrix (perspective/orthographic)
-Set view matrix (lookat/up/pos)
-set world matric (you mess around with this to move meshes)
-Render mesh.
