The quickest way would probably be to go to 'Preferences' > 'Movies', make sure that 'Lookup: Using Folder Name' is checked, renaming all the movie folders back in the Finder to 'movie name (year)'.
After that you can use 'Fetch Metadata' to process the left over files.
For TV Shows I can only recommend to make sure that you only put folders with exact TV Show names in your TV Shows folders, and put your episodes in those folders.
Another method might be to put a 'tvshow.nfo' or 'movie.nfo' / '<moviename>.nfo' file with just the IMDb ID inside it into the correct folders, I think ViMM is able to pick up on that and use it to search for the correct items, and it probably wouldn't be as quick as make sure the movie/tv show folders are as accurately named as possible.
