Yes, your console can get banned if you are found cheating online.
No it will not. except when it does instead get banned because yes hacking can get you banned
It is not one of the reasons listed for being banned. You might want to review the related question and it's PlayStation Network link anyway.
Yes it is one of the items that the PlayStation Network has that will allow you to be banned and called Offensive Image or Audio see related question for expanded reasons for being banned
You can get banned, but not everyone who does something that can get you banned is actually banned. You have to decide if it is worth it to take that chance. Im not really sure, but what would make the most sense is that you could get banned for moding online play. you should be fine moding offline though. (I really hope this is true.....)
