I could definately see Sharundabald running across Kyriel before, and from you brief description he would probabaly remember her. Up to you as to whether she remembers him. He's a fairly memorable person, it's the yellow eyes and very.....insistent personality. He spends a good amount of time working with or for the church, including retrieving tomes of lost information for them so they could have met in a professional capacity.
As for Baden, Sharundabald is one of those followers of Ioun that thinks spreading knowledge is almost always good, so if Baden is willing to trade in knowledge then he would find Sharundabald, "Sharun" to friends, a ready source.
Sharundabald has heard of Barek, he read up on wellspring before coming to town and noted his shrine with some interest, but they probabaly have not met as this is his first visit to the area.
