Actually, I doubt Emma is in the Dark One's vault. Since the Nevengers (minus Emma) possess the dagger, I don't think it would be that hard to just "summon" Emma. Now, it is possible that she teleported out of Storybrooke altogether, meaning she is not in range. But that would likely mean back to the Enchanted Forest.

As for if Emma is strong enough, with the DO's power, combined with HER power, She is probably strong enough to create a portal. I mean, let's face it, the Apprentice was able to generate a portal, while in the LWM. And I am willing to bet that Emma is stronger than the Apprentice now, and maybe an equal match for Merlin. It's even possible that Emma left for NYC, Boston, London, Pukhat, or some other destination in the LWM. and if she can have magic there, she has a significant advantage over the others.
