That web page deals with purely radial motion, explaining how the acceleration is expressed in terms of Schwarzschild coordinates, but another page from the very same site gives a simple derivation of the equations of motion for general motion, which seems to be what you guys are interested in...

Most of the observed precession (about 5557 arcsecs/cent) is simply due to precession of the equinox, and another 532 arcsecs/cent is due to the pulls exerted by the other planets. These effects would be virtually identical for both Newtonian gravity and general relativity. The remaining 43...

The effect of spatial curvature on the rate of deflection of the path of light is not proportional to the slight difference between r and rho at any given point, it is proportional to how that difference changes along the path. Notice that, at the point of tangency, that difference isn't...
