Answers:

1) Sontarans.

They just don't have a lot of potential.

2) Three seasons.

That would give his character enough time to change over the course of his run and three seasons seems like the best amount of time to go, not too long, not too short.

3) Season finale.

Will make the finale more epic and leave the readers anticipating the finale, like me.

4) Atraxi.

Interesting race, not really well explored.
