Gil sink, Sarah, and Soldier Job...

I'm at work and can't shake these thoughts. Anyone got answers?

1. We are all millionaires at this point. Will there ever be a proper Gil sink or should we just spend with reckless abandon?

2. What's the deal with Sarah? Do we ever find out if she's bad news and what's her back story with garland?

3. Dafuq man. What's the best way to approach this? Ability 3 or 4 summons? At 2 summon cards a pop are my chances of getting the legend job higher?
