Answer 1

You should consider using a Wizard style approach. There are a number of articles on how to do this on codeproject.com. I've had luck with this one:

Answer 2

Since all your form are modal (ShowDialog), adding a this.Close(); after each call to Dispose on the child screen will close the direct parent:

Form G = new Screen1();
G.ShowDialog();
G.Dispose();
G.Close();
this.Close();

But you have to do this on screen2 and screen3.

You could also implement a class that will manage the opening and closing of child screens instead of doing it in each screen. This approach works well if you can chain the screens as some sort of wizard.
