I'm pretty sure praying is the least useful thing to do in your list. Completely useless, I'd say.
If we assume that some decent God exists, (s)he's surely aware of what is going on. What's more, it could entirely be her/his will. I'd be very upset if someone tries to convince me to undo what I have decided to do for reasons only known to me. Thus, praying may actually have the opposite effect.
