Answer 1

To do this, you need to simplify the access information - by loading it into the database, and then output it from the database to GeoJSON - dividing it into tiles, or in its entirety - for the desired area.

You can, of course, set Mapnik on the base, but I would output the vector - it's easier to work with specific objects with it - without needing to contact the server again.
Actually, everything is written here how to convert the entire area into GeoJSON without dividing it into tiles https://wiki.openstreetmap.org/wiki/GeoJSON

Answer 2

No way. You don't need it. You need either ready-made tiles or vector data in GeoJSON.
