There are v.in.ogr and v.out.ogr which support these formats:
http://gdal.velocet.ca/projects/opengis/ogrhtml/ogr_formats.html
+ GML which is not in above list

Yes, they may be interesting.

Yep. And above i.tape.tm3 might be hopeless outdated. r.in.gdal
supports CEOS and LSAT FAST format (and more).

Yes, there is not much point in replicating cs2cs functionality.

Yes: ogrinfo:
http://gdal.velocet.ca/projects/opengis/ogrhtml/ogr_utilities.html

so it's not needed (OGR supports TIGER).
