In the last chapters of the book, Tea Cake bites Janie. Does she then have rabies, and is she coming home to die?

My opinion is that, since the author made no reference to Janie getting the rabies treatment shots, that she, in fact, does contract rabies and chooses not to get treatment because she doesn't want to live without the love of her life, Tea Cake.  Perhaps Hurston purposely left that part in ambiguity so the reader could write their own ending.
