I'd download the latest version of the quests tarball. Not sure why there are : in any of the quest file names though.
You need:
/server/plugins
/server/lua_modules
Both directories will be in the quests tarball you unpacked. (e.g. /quests/plugins and /quests/lua_modules)
/server/shared
will contain memory mapped files (
http://en.wikipedia.org/wiki/Memory-mapped_file ) when the server is first started up. It's basically a cache of items and other "base" data that the zone processes use.
