High Elves and the Balrogs

Eexactly. Nevertheless, it's a wonderful demonstration of her power...

But let's not forget our main topic. I think, as much as Galadrielist I am, you can see her not expressing any fear of the balrog of Moria when she hears the news (actually, I sort of suspect her of knowing more than she says, and so maybe even knowing about the presence of the balrog), quite differently from Celeborn, for whom it's not only a new information, but also a thing that scares him, or at least that's how I always took it.

And if it were possible, one would say that at the last Gandalf fell from wisdom into folly, going needlessly into the net of Moria."

In regard to Galadriel throwing down the walls and laying bare the pits of Dol Guldur, this is more extraordinary in the fact that she accomplished the feat after the One Ring was destroyed; thus, I would think the power that demolished Dol Guldur was innate and not necessarily due to her wielding the ring Nenya, whose power would have waned after the One Ring's destruction.

Raynor, with regards to protecting Lothlorien I would say she had the aid of Nenya. As that was the purpose of the Elven Rings. However, the Elven Rings were not made to enhance it's bearers power, so any display of power 'or magic' of Galadriel I would say was all her own ability. As the Elven Rings did not lend out power boosts in the way the One Ring was made to do.

Just as I would argue the benefit of Gandalf bearing Narya was not in giving him extra power to fight the Balrog, but assisting him in his 'weariness,' exactly as Cirdan said the Ring was for:

'Take this ring, Master,' he said, 'for your labours will be heavy; but it will support you in the weariness that you have taken upon yourself. For this is the Ring of Fire, and with it you may rekindle hearts in a world that grows chill.'~Appendix B: Tale of Years; The Third Age

Exactly. Nenya was in the first place the thing that caused Lórien not to wither; and as Sam felt it:

Yet if you succeed, then our power is diminished, and Lothlórien will fade, and the tides of Time will sweep it away.

It was also what kept its borders safe - I'd also think that for example the white mist that covered Eorl's ride to keep them secret and safe from Dol Guldur was the work of the Ring.

For when at last the host drew near to Dol Guldur, Eorl turned away westward for fear of the dark shadow and cloud that flowed out from it, and then he rode on within sight of Anduin. Many of the riders turned their eyes thither, half in fear and half in hope to glimpse from afar the shimmer of the Dwimordene, the perilous land that in legends of their people was said to shine like gold in the springtime. But now it seemed shrouded in a gleaming mist and to their dismay the mist passed over the river and flowed over the land before them.
Eorl did not halt. "Ride on!" he commanded. "There is no other way to take. After so long a road shall we be held back from battle by a river-mist?"
As they drew nearer they saw that the white mist was driving back the glooms of Dol Guldur, and soon they passed into it, riding slowly at first and warily; but under its canopy all things were lit with a clear and shadowless light, while to left and right they were guarded as it were by white walls of secrecy.
"The Lady of the Golden Wood is on our side, it seems ,” said Borondir.

But I don't think Nenya gifted Galadriel with much power of her own, as Boro suggested. For it was not the purpose of the Elven Rings, as Elrond says to Glóin:
