So, you could do this lots of ways. You don't need a connection EditPart,
maybe just a PolylineConnection. Such a connectoin could be added by the
editpart, or even by some custom figure that the editpart uses. But, it
could be even simpler than this. If you know exactly where the line will
be, for example you are doing something like a Tree, You could just draw a
line down the left side of the Figure, or even use a Border which paints the
line. I'd have to see a mockup to offer more advice.

Not for a draw2d connection. You just need a line with two
ConnecitonAnchors. Don't worry about GEF connectoins unless you need
something that is selectable, and the user can delete, bend, reocnnect, etc.

This is fixed in the latest code. A new ZIP will be available soon, or you
can pull the source from the CVS repository.
As a workaround, you can do:
node.setMinimumSize(new Dimension(10,10));
