--min-size-polygon=NUM
   Removes all polygons smaller than NUM from the map.
   This reduces map size and speeds up redrawing of maps.
   Recommended value is 8 to 15, default is 8.

     Generate a POI for each polygon and multipolygon. The POIs are created
     after the relation style but before the other styles are applied. Each
     POI is tagged with the same tags of
     the area/multipolygon. Additionally the tag mkgmap:area2poi=true is
     set so that it is possible to use that information in the points style
     file. Artifical polygons created by multipolyon processing are not 
used.
     The POIs are created at the following positions (first rule that 
applies):
        polygons:
            * the first node tagged with a tag defined by the 
pois-to-areas-placement
              option
            * the center point
        multipolygons:
            * the node with role=label
            * the center point of the biggest area

Does this solve your problems?
