Yes, you will need to for JavaFX 8 since there is only one vertex 
format. We have plan to add more in future releases.

Yes.

  Flat shading isn't in our plan but we may consider it if you have a 
good 3D use case. Can you elaborate your question on smoothing group number?

No, we didn't specify much about its restriction. It may be good to keep 
this within a small positive range. We may have to tighten later as we 
work out some of the details.
