Overlaying the surface contours on the anatomy & functional is something I would do once with a project, just to make sure there are no misunderstandings with the orientation and origin settings. But once you have a processing stream going where everything has been processed the same way, it's not necessary to do this for each mapping.
But yes: If I had SPM8 data, I'd use the SPM5 atlas option.
