Andrey,

You may use the -sql option to select a particuar shape type to be
converted:

SELECT * FROM table WHERE OGR_GEOMETRY='POLYGON'

for more information about OGR sql see: http://www.gdal.org/ogr/ogr_sql.html

Field names can only be maximum 10 character length with the shape format.
I'm not aware of any workaround to this issue. You may however rename the
fields to a more reasonable 'short' name by using the OGR sql field name
alias option, see the document referred above.
