I think I never used any Shadow World module out of context. But then again, I never used any adventure idea published for Shadow World either - I picked whatever material I wanted to use (NPCs, floor plans...) and weaved it into my own plots.
Basically, everything is just raw material for inspiration.
The things I get the most mileage from are the campaign modules, because of the maps and cultural info, and the master timeline which I twist and complete as I go.
