I spent quite a while working through this problem myself.  When you export
a 3ds object as a dxf file the texture information is not stored in the
dxf.  When you run dxf2rsd it creates the rsd file(s), one of which is a
.mat file.  This file has color, shading, and texture mapping info in it. 
You can edit it in a standard text editor, or you can get RsdTool.  RsdTool
looks like it will be a very good tool when it is done.  It is fairly buggy
(don't even try using it under NT 4.0, even with service pack 3), but it is
a hell of a lot better than having to edit the .mat files by hand.  As for
the boolean shapes, I don't know for sure, but I'd say the problem is 3ds. 
I've seen 3ds have some crazy results with boolean operations, and
exporting a boolean object to a dxf file can't help the process any.  Hope
this has been some help.
