6) Correct. The shrine bonus is effective from the moment the 3rd shrine of the set is built, for the rest of the game regardless of which player controls the planet later in the game. However for the Lyra player to gain the vp bonus at game end, they must control the system that the shrine is in.7) I don't believe the planet has to be populated to build a shrine, just controlled.
8) Correct. Although the only benefit to this would be for the sake of depriving the other players from WG technology, and given the amount of resource investment that shrine building requires, this may or may not be an effective strategy.
9) Correct. At the VERY beginning of the upkeep phase. Obviously because of this, you can NOT use newly acquired resources to build a shrine, as those resources have not been gained yet.
This can however be useful because it allows you the freedom to build a economy shrine in order to enact strategic bankruptcy.
