Hi Mark:
What you have paired with the Iron Cross 2nd Class is the Ehrenkreuz (Cross of Honor) 1914-18. The Ehrenkreuz, sometimes referred to as the Hindenburg Cross, was instituted in July 1934 and available in three grades: combatant, noncombatant, and for widows of the fallen. The Ehrenkreuz was the sole official national award commemorating service in the Great War.
Though it was meant to precede, when mounted, all other state awards, the Ehrenkreuz would never take precedence over the Iron Cross. Though the mounting of your first example appears old, it is not, as you identified, correct. Furthermore, the presence of swords on the ribbon is superfluous as they are already present on the cross. Whoever is responsible didn't know what he was doing.
The Militärpaß appears to be of the type issued by the Kaiserliche Marine.
For taking close-up pictures, you will need to set your lens for macro photography. The universal symbol for this setting is a flower. there should be a corresponding button for this with the camera's controls.
Happy shutterbugging!
Chas.
