Try "Save All As...".
If I am not mistaken settings are meant for individual nodes only.
But internally Settings, Subnetwork Settings,Copy-Paste, the .comp it self, and Macros:
All the same format (minus some features in macros, comp settings in comp etc.)
So if you "Save All As..." to a macro folder you can easily spawn the whole network.
As to the icons: place a .bmp with the same name next to the node.
