Noob questions

Hello, I'm kinda new to PS4 hacking and I wanted to be sure of certain things. I would be happy if you could help understanding those:
-Webkit exploit. Run unsigned code like Homebrews but not game backups ?
-Kernel exploit. Install unsigned code, run it, run game backups, CFW and heavy software modification ?
-Jailbreak. Everything above plus installing game backups ?

Is there somthing wrong ?
And also what are we waiting from qwertyoruip ?
Thank you for any help you could provide...
