Do a Google search for "SAFA checklist", you'll find all you need. Download the document, and prepare a SAFA binder with copies of all documents, and a document control page, showing expiration dates for insurance etc.
My belief is that SAFA inspectors are professional, and have a specific plan when they show up to your aircraft. As long as you can produce the items on the checklist, they are easy to work with.
My two cents is that much of the banter you hear and read about difficult inspectors is not based in fact, but imagination.
