Answer 1

In my experience, there is no a general rule to decide this kind of things, it depends on the usability of your future App...

Navigation controller helps the user to remember where they are in every moment, and how they can go back, but could not be the best thing to use if you have too many levels... And more important, if you are using a NavigationController or a TabBarController, you have a class, accessible from all the other ViewControllers where you can have general functionality or data...

The difference between the modal and push segue is that in the first you will always return to the parent ViewController, because you are only showing new information on top, while in the push one you are replacing one ViewController with other...
