As to the travel issue, it sounds like that may be cleared up to some extent as she apparently just gave you the travel itinerary. For the future, you should consider sending her a certified letter indicating that you expect her to abide by the court order regarding disclosure of all travel info. In the letter, you could indicate that any future violations will result in a motion for contempt. A judgment is only as good as you make it. As such, it is incumbent upon you to enforce the order.
As to the step-father, your recourse is similar, the filing of a motion for contempt. If you have a court order stating that the step-father is not supposed to be involved, then you should provide the mother notice that she is violating the court order and then, if there are any future violations, file a motion for contempt.
