It doesn't matter how big the listfile is. Size doesn't mean it's good, it just means it has a lot of names. It's a really good idea to make a listfile for the map in RMPQEx, because it will have a lot more of the names of that particular map, instead of a lot of names that aren't in it.
The imported files are probably not being put in the new one due to missing filenames.
The object data, probably not. Is the map widgetized?
You can always extract the custom object files from the original map, and import them into the deprotected map in WE. Object Editor>File>Import Custom xxx Data... (xxx changes based on tab).
