More Than Human/Headscratchers

How and why were the Rowdyruff boys freed from Him?
Brick hints that he had to go through hell (I can't remember the exact chapter) once before when talking to Blossom. Brick also shows, especially in some of the newer chapters, that he has some sort of connection with Him, despite the fact they don't live or work for Him anymore. How did the boys get their freedom?

How did the boys end up working for JS Inc.?
Was it a money issue or something else? I'm thinking money...
