One theory I had, in answer to your first point, is that the Galactic Civilisation referred to as the Protheans by the Citadel Races in the present could actually consist of more than one race. I know there is nothing in the canon to suggest this but there is also nothing to the contrary. After all in the current timeline of the games there are 15 sapient races on the galactic stage (12 if you take out geth, yahg and vorcha but still). Therefore it is logical that there could have been several sapient races at the time of the Protheans, with the Prothean character and the Ilos statues both representing different races.
