I haven't tested, but it looks sane. Just a few comments:
- printf("\tERROR not enough bits left after wb\n"); this is actually
now an error. It just means you got to the end of the frame
- I suggest speex_get_num_frames() instead. That works for both
narrowband and wideband. Number of samples could be misleading because
of nb vs wb frame size.
- You can change it to use the nb mode info in modes.c, but leave the
wideband like it is now. Otherwise, it would cause the wideband stuff to
be linked in all the time.

I don't understand your question.
