I'm sorry but I still have no idea what you're talking about. You've described PCM mode but not explained what "short frame sync" and "long frame sync" mode are.
This diagram may explain things better: http://picpaste.com/pcm_fs-7dBlrkuW.png
Sorry, that's not really clarifying things. It looks like "long frame sync" is just I2S but presumably there's some difference?
Yes, in I2S mode, according to the spec I have, the frame sync leads the MSB of the data by 1 bit clock cycle. Whereas the 'long frame sync' mode starts with the MSB of the data.
