The big 'secret' to ally achievements, if I've heard right, is that you can't do any of the side quests on the Citadel before you can get off of it. Get all the party members you need, then start on the Citadel with the small sidequests.
You need to do 10 missions, and 45 side quests for the achievements.
So I'm not sure what combination you need to do (ie, not take Liara to Noveria to meet mommy Benezia). Nor do I know if ally achievements unlock if you re-use the characters on a second playthrough.
Back from the dead, I'm afraid.
