Yes.

More or less.  Although it's less configurable from
elisp since more of the behavior is implemented in C (more specifically
in the toolkit code).

It should also be compatible with "the way these scrollbars work in
the given toolkit used".  So if you use Lesstif (or Xaw3d with arrows),
the bindings are not the same as the ones for non-toolkit Emacs (e.g.
mouse-3 does not scroll back).

I don't think so, because in many cases making the scrollbar work
like non-toolkit Emacs (rather than the "native" behavior of the
toolkit) is difficult and I'm not sure it would be what users want.
