Ambition: Nemesis question? (spoiler warning)

So after a while of waiting I finally got to go to the Iron Republic and do my ambition Nemesis stuff there and a good while after that but the only problem is I did everything before the Iron Republic a real while back and kinda forgot what happened, can someone give me a rundown of the pre-iron republic content?

The format is not ideal, but the easiest thing is to look at the wiki entry.
