In regards to your last idea, I felt that this is exactly the sort of thing that has been building.

First, Clan Urdnot. You have several chances to strengthen the Urdnot Alliance and strengthen your allegiances with them.

Secondly, the Geth. You get a chance to strengthen the Geth with Legion (covert the Heretics), and influence Geth/Quarian relations. That is, to go to war or not to go to war.

Thirdly, the Rachni. To have them survive or to kill them off.

Forth, the Alliance. Your choices could seriously increase the strength of the SA (all human council, carrier-class etc).

We know that our decisions from ME1 and ME2 will effect ME3. I think what we have been doing is making the beginnings of an army. It's pretty clear that the Alien Council is going to be completely useless in stopping the Reapers. I think in ME3 we will see the Reapers descend on an unprepared Citadel Space, and at the last minute a massive fleet of Krogan, Geth, Rachni, Alliance (and maybe even Mercs if your Aria DLC happens) swoops in (lead by Sheppard) and saves the day (or doesn't as may be another ending).
