I don't understand this question. Using a transparent texture seems the best way to get a circular shape on a box billboard. But I don't understand what you mean about 3D and 2D stuff there? > 2.

Moving a billboard in the Z axis is similar to changing the size of it (i.e. perspective projection). So yes, it is possible to do this using billboards but perhaps in your case a simple mesh would be better as it is easier to move that in 3D.
