I am really not trying to villainize - why does everything come across wrong?
Alleging she was cheating on you for the duration of your relationship without any new evidence is rewriting history. As I said before, LBS do it almost as often as WAS. That's not surprising, as unlike WWS (aliens!), WAS and LBS are both humans. They're both doing their best with the cards dealt to them.

That doesn't sound harsh, that sounds normal.

Maybe, maybe not. You're not responsible for her choice to speed. You're also not a traffic cop. My father's never faced the consequences of a speeding ticket, and he definitely speeds.

Yes, be selfish! You two are no longer in a relationship. You are competing for limited savings and income. If raising one of these points wins you more savings or maintenance in court than it costs your lawyer to make the point then by all means bring it up. If it doesn't, then let it go. Most things will fall into the "let it go" territory. Typically your final settlement will be close to court guidelines.
