Very nice summary! Upon first reading, apart from a few minor grammar mistakes, I have just one comment/question concerning the field equation. The special property of the einstein tensor, that it is covariantly conserved, seems only to be linked to local energy conservation once one has decided that the other side of te equation should consist of the energy momentum tensor. Before that its just *some* conserved current. In your text this order is reversed and I'm not sure whether the argument shouldnt better start with T for that reason...
