I thought it was a good episode. However, I didn't like that the Reverse-Flash decided to have Rip tortured. I think he should've been able to understand that Rip used the Spear of Destiny and no amount of torture would get what they want out if him.
That's a toughie.
He merged with his past self.

The Supergirl episode was barely a part of the crossover. And yes, if you watch them in the order that they aired, you will be watching them in canonical order (mostly).
He's most likely just going to be a past version.
Hasn't it already been confirmed that Flashpoint brought her back to life?
Yes.
Yeah, the Supergirl episode wasn't really a part of the crossover.
Iris!
I don't think that is how he will return.
