Hi,
You can do that with Global Mapper itself. Export raster to web format, choose osm format.

Hi,
Take 12.02 at least, or the new 13.0 for export to osm you can use trial version.

Hi,
You should use OsmandMapcreator to make a sqlitedb package. You can use the png files then. Create a new mapsource then.
You can also use Mobac for that. You have to create a new xml mapsource definition and subfolder with your pre-made tiles. You can even preview your tiles then!
Please search Google group osmand on the word Mobac for more details.
