Basically, my understanding is that since Vimeo will always recompress your file, the highest quality will come from 720p MP4/AVC at the highest bitrate you have the patience to upload.
I don't think you chose a format that will avoid the recompress - if anyone knows otherwise I would be interested to hear.
I believe Vimeo will leave 24p, 25p, 29.97 and 30p intact. Not sure about higher rates - anyone?
