I think that the short answer to your questions is that FortranForm is a very old component of Mathematica that I suspect has not been updated since version 1.0 (and toe documentation indicates this). So, for question # 1 the answer is no. For question #2 you need to write a function of your own that searches out exact expressions and substitutes the numerical values with the appropriate precision & c.
