I think the passage with the mirror of Galadrial and the descussion between Frodo and Galadrial about the rings of power make it quite obvious.

Where in that passage does it say that Nenya granted Galadriel power over water and mist?

Was it Vilya that allowed Elrond to floud the fords of Rivendell

It is not textually suggested. The Rings of Power "enhanced the natural powers of a possessor" so if any influence of Vilya can be inferred, it would be that Vilya merely improved Elrond's ability to do something he could have done with out Vilya.
