Partial answer to question 3:

  In general relativity the statement that gravity bends light and the
statement that matter distorts spacetime are equivalent.  That is the 
whole point of general relativity; that the mechanism of gravity is the
curvature of spacetime.  I am not familiar with the non-relativity theories
of gravity, so I can't comment on what explanation they give for light bending
around the limb of the sun (or any other massive body).
