A couple of things:

I think you can get nearer to what you want by using the "Keep with Next" function in your Styles.

I would suggest you change your "SLUGLINE_UL" style to include "Keep with Next" under paragraph settings. That will mean that line will not get orphaned at the bottom of a page but always stay with the ACTION section that follows it.

The same will be true of the Character style with the Dialogue style. You don't want STEWART to appear at the bottom of a page with his line of dialogue on the following one. By making those character styles "Keep with Next" that should help with this.

You don't have very long sections of dialogue. I experimented by repeating one line over and over, and it does split across to the next page.

As to the page numbering, in your header and footer settings, "Different First Page" is selected. That will mean the first page doesn't match the following ones. You can deselect that, but make sure you copy the footer you want on all pages first, and have on your clipboard. I think it should give you what you want, but just in case changing the footer settings would erase the one you wanted, you'd still have it on your clipboard to paste back in. I'm actually not clear on whether you wanted your first page to be zero, or one, or nothing. I'm in the US, and have never heard of the second page being page 1 unless it were a cover page of some sort. But, I also don't deal with scripts.
