That article is a bit confusing. The TYP file is not the mkgmap style file. The style file is this directory here: http://svn.openstreetmap.org/applications/utils/export/garmincyclemap/network/cyclemap/
So download all of that, then mkgmap should find it.
Use tile splitter to split up an osm file into smaller pieces. http://www.mkgmap.org.uk/page/tile-splitter
