Sounds like a dreadfully dull "story" to me. I don't mean to seem overly harsh, but the single most "distracting" element in a movie (or book or play or opera, etc., etc) is a poorly contructed story.
The best manipulation, sets, costumes, puppets and such are completely meaningless without their ultimate purpose being to serve the story.
Study how Pixar films approaches their work. Story comes first. Period. They often come up with great gags and sequences that are never animated because ultimately they do not add to the story.
Mysterious goings on between rival tea rooms run by monsters and grannies really does not sound very compelling. If one or the other gets all the customers, well.... so what?
Having a good story can help cover a lack of production value. I recently directed a play that has a scene in the woods between the young lovers of the story. As written, the scene is played in front of an extremely simple backdrop, consisting almost entirely of strips of green and blue cloth, and a carboard moon. The reason it works in this play is because the characters and their story take the audience to the place where they "willingly suspend disbelief" to engage in the story. If a weaker piece were to be played in an identical setting, both would become laughable.
A good story can be summarized into just a few paragraphs, conveying all of its important intentions. If you cannot write a simple treatment of the story, it's quite simply not ready for pre-productioni, let alone production. If your above description is the best you have, then it's not ready. Not even close.
In short, write it, rewrite it, dissect it, sharpen it, check it for spelling and grammar, make sure it is a story worth telling before investing ANY energy into making a film.
THAT's the biggest tip, not rehearsing.
