we are using Richard Weait Tutorials (genearate_tiles) for world wide map, what do u suggest?

do we make it for a zoom level = 12 or 13?

It depends on the rendering system used. See: 
Tile on avg served by tile.openstreetmap.org: ~6.5KB. opencyclemap.org: 
quoted as being at least 4x bigger.

generate_tiles.py method will generate many many tiles that will never 
be viewed, limit to zoom 17 and even with hard-linking identical sea 
tiles you will run out of disk space.

mod_tile can comfortably be used with 500GB of space, as long as disk 
can keep pace and ancient tiles are expired.
