The 6H analysis period will start right after you finish the 2 events at 1.3. You can't use the car nor upgrade it while analysis is running. All you can do is service it.

You can't skip by watching ads, but you can for gold (15 GC IIRC).

The countdown does continue even when the app is closed.

That said, even if analysis prevents you to complete 1st day in less than 24 hours, you still have 6 days to catch up. So there's no reason to worry at all.
