Re: GPL/LGPL confusion
I am not a lawyer, so please do not rely on this as legal
advice. I am also not a Debianite, but I will cc this message to
debian-legal so they can avoid duplication of effort.

Yes. The restrictions of the LGPL are a subset of the
restrictions of the GPL, even when it comes to the right to add
remaining restrictions of the GPL (due to section 3 of the LGPL),
so it does not violate section 6 of the GPL.
However, as your allude to in your second question, if your
library requires the GPL'ed library, the net effect will be almost the
same as if your library were GPL'ed. It will only be legal to link
GPL-compatible programs with your library (this includes more than
just GPL'ed programs,

As a matter of politeness and good documentation, yes.
