Mercury's orbit not matching Newton has nothing to do with the speed that gravity may, or may not, travel at, but everything to do with time dilation close to a massive object like the sun.

Until we can accurately correlated gravity waves (only recently detected) with an optical signature, etc, we won't have any evidence to corroborate the speed of gravity.
