You must have the page scaling set to "Full screen", not "Fit Screen". Otherwise the aspect ratio wouldn't be distorted like that, so check that real fast. Send screenshots of what you are encountering to mike@zubersoft.com if things still aren't working the way you expect, along with a screenshot of your page scaling settings and display mode settings.
As far as applying zooming to multiple pages in a setlist, yes you can do that. Load your setlist, bring up the overlay, tap the second icon at the bottom left, tap "Zoom/Pan Settings" and change the Zoom Settings dropdown to "All Pages in Setlist". Then you can pinch zoom and all pages in the entire setlist will be adjusted. Just ensure all of your pages are actually the same size, otherwise you may not get the result you are expecting.
