I'm not sure I understand what this has to do with your question.  It seems unrelated.

That is expected. Use gdaladdo if you want overviews (zoom levels).

You use the creation option that matches whatever you need. Tile scheme is not really  about creating overviews.

It can be in any SRS you want. The geopackage spec makes it clear that the tiles can use any SRS defined 
in gpkg_spatial_ref_sys, and gpkg_spatial_ref_sys can contain any EPSG code you want to add. It works
in GDAL,  just use -a_srs option to gdal_translate. Or reproject the source data - whatever works for you.
