A dependency on the libstdc++-dev package is not (yet) needed, as
every new major version of gcc comes with a new libstdc++XXX-dev
package. Maybe it's better to depend on g++ (>= 3:3.3-1) or a specific
g++ version if yoou need it. I'll file a report on build-essential to
tighten this dependency.

Yes. No (modulo bugs). You can check this by comparing
  /usr/share/doc/libstdc++5-dev/README.libstdc++5-baseline
and
  /usr/share/doc/libstdc++5-3.3-dev/README.libstdc++5-3.3-baseline
