Sorry i can't answer all of the questions completely.

As for the first one, I dont know the drop rates of the gems particularly, but your cards' lesson skills may play a part in what's happening to you?

For the 3rd, i've been told that you should want your teams to get at least to 200,000, but i guess the more you have, the better it should be(?)

4th: It seems like that's what they're doing for the past few events. At least they're rotating the other cards, though it'd be nice to see change in the lives.

5th: I dont believe the older event cards will be obtainable currently, at least until April 2016 where the loop will occur. (Limited Scouts are available awhile after they're release, however) In a recent announcement, it was stated they are thinking of "adding a way to 'experience new events again', including being able to read old event stories, and, yes, obtain past event cards." from here
