I have attempted to answer Questions 1 and 3 here: https://github.com/geopaparazzi/Spatialite-Tasks-with-Sql-Scripts/wiki/Project-1811-gdal_question
I will start on Question 2 now, since I have not used gdal_rasterize that often. A quick answer is however, 1) gdal_translate -of PNG -a_nodata 192 ../sources/1811.Neuester_Grundriss_von_Berlin.5800.3068.tif 1811.Neuester_Grundriss_von_Berlin.5800.3068.png 3) gdal_translate -of PNG -a_nodata 192 -projwin 24800 21300 25800 20700 ../sources/1811.Neuester_Grundriss_von_Berlin.5800.3068.tif 1811.Neuester_Grundriss_von_Berlin.5800.3068.area_rote_rathausturm_panorama.png Mark Johnson, Berlin Germany
