Feel free to rearrange, cut, add, give links, whatever: personally, I'm interested in securing the whole box, meaning how to glue things together in the safest possible way, without forgetting anything, while things like how to make Postfix not an open relay, for example, are already covered in detail in the Postfix docs.
I have found that the checklist/scripts/documents at http://www.cisecurity.org/ are a pretty good starting point.
