In your first point just remeber that cerberus get all the control tech after the events at the collector base or at least when ME2 takes place, before those times we don't know anything about Cerberus-Reapers conections. After TIM gets all this reaper tech into his body I can force myself to believe about some kind of direct control in the nearby people even without implants...

The second question is far more easy to answer. They didn't give us the investigate option from the beggining of the game they just tell us what they want and we go ahead. The investigate options are severely cut down in ME3 and that is really sad. This may be forced in order to give us that sensation of hurry because the galaxy is going to hell. In my first playtrough I lost many missions because I went quickly to the citadel when the salarian councilor told me about Udina and I assaulted sanctuary and cerberus HQ after Thessia because I wanted revenge. So for the first playtrough the lack of investigate points fits well but when you play again it looks poor.

For the final point... Maybe (and it's just my toughts wich is sad but it's what we got right now) if Wreav leads the Krogan the galaxy faces new krogan rebellions depending if you cured the Genophage, the geth can't be trusted if Shepard and the quarians are dead, the rachni attack again... many variables unanswered because of lack of effort in the final moments.
