Can't answer your first question. However, there is a story arc in Roberto Aguirre-Sacasa's Marvel Knights 4 that involves the Inhumans you might want to check out, particularly after reading Young Inhumans. (It came after, and was influenced by, YI.)
Ok, thanks. That sounds like issues #19 & 20, which are collected in Marvel Knights 4 Vol 4: Impossible Things Happen Every Day TP. Hopefully those two issues are worth the collected edition.

If it's true that the Pacheco/Marin status quo for the Inhumans was just discarded off-screen, that's a shame. Especially given the latest resurgence of cosmic-oriented stories.

Thanks for your help!
