Is it necessary to have a zbuffer if you use Direct3D only as DirectDraw with hardware supported sfx. I'm not planning to use the z-axis...

No. ZBuffering is only good when you want
to sort the nearest and far away polygons.
If you dont intend to use the Z axis you
shouldnt need to use the Zbuffers.

You can disable z-buffering by setting the D3DRENDERSTATE_ZBUFFERENABLE state to FALSE.

You may want to use Z-buffer in the 2D app though, it could be any easy way to support multiple layers, parallax scrolling, etc. Just make sure all your polygons for a single layer have the same z.
