Whilst there is probably a unique TLC number for decorated parts, the LDraw
convention is to use a Pxx suffix to the part number, based on the ranges of Pxx
numbers documented at http://www.ldraw.org/library/tracker/ref/patterns/. In
this case p01 is appropriate. I'm assuming that the 443.. numbers are moulded on
the parts? 44336p02.dat is OK for the second variant.

Yes please. Type 2 commands (lines) should only be used to instruct the renders
to generate a line at the join of non-coplanar regions. Also (although
challenged by some) these are allowable completely inside quads of patterns to
ensure the fine detail shoes at low-res. They should not be used to delimit
different colours in the same plane.

Yes please do this as a subpart. The subpart should be named s\443NNs01.dat
