It is the usual configuration for the Arduino to control everything, that's why they call it a microcontroller.
You may have to show the products you intend to use as I for one am not familiar with a "stone LCD" nor an LCD that "controls a microcontroller."
There are many Arduino LCD and LED controller programs and projects out on the web already.
Have you searched there..?
Reason being the sketches will already have been written and tested to a large extent.
No one here will write programs for you ....well, at least not for free.
