If i want to use vertex shader, do i have to extract out the vertices and indices of the mesh then set the shader and render using DrawIndexedPrimitive, or can i set the shader and call DrawSubset?

The latter. The shader will automaticlly pick up anything rendered between BeginPass() and EndPass.

calling DrawSubset on D3DXMesh will just set the index and vertex buffer and call DrawPrimitive for you. any other device/render states you've set or D3DXEffect has set for you will be applied to what you're drawing.
