Answers:
1) The following are all confirmed predictions of GR:  changes to the precession of Mercury's orbit, reddening of light traveling away from the Earth's center, deflection of starlight by the Sun, orbital energy loss in neutron star binaries, and lensing of light from distant galaxies by nearer galaxy clusters.
