* All DVD's have a static menu's with audio, and will be DVD9's.

This is what I am shooting for, and as far as audio bitrates, I am not sure, like to keep as high as I can obviously, but I am limited to what the DVD will let me(total max bitrate), so final bitrate I will only know once I get them authored up and see, hope this helps somewhat LOL.
