Hi Sarah,

Somebody with more expertise on rotation than me will hopefully be able to chime in, but I you should be able to get a good start by reading

section 6 in the second MESA instrument paper: http://adsabs.harvard.edu/abs/2013ApJS..208....4P <http://adsabs.harvard.edu/abs/2013ApJS..208....4P>
section 4 in the fifth instrument paper: http://adsabs.harvard.edu/abs/2019arXiv190301426P <http://adsabs.harvard.edu/abs/2019arXiv190301426P>

In particular, that latter reference has some nice figures that should help answer your question about how oblate the star gets.
