IaMD also implies Denobula as a UFP member, since Phlox said about Earth, Vulcan and Denobula being united in a Federation in the 'other' (normal) universe or something similar.
I'm looking forward to updating my UFP aliens site when the new movie comes along!

I haven't seen too much contradiction. I generally go with FASA's "ST IV Sourcebook Update" unless the novels have clarified something.
