When given two ridiculous choices, choose the most ridiculous. What was the name of the monk Bhaalspawn, Balthazar? Or do you mean Melisandre or whatever her name was. I guess that makes some sense, it might also help work in the Hell angle. Throne of Bhaal was a bit forgettable for me.
As for Shar and her reveal, I think her reveal can be the SH reveal. It could be better done, everything can (especially in an EA), but in a game where every scene has to go through a rubric of what kind of character you've decided to roll, you have to make a game that works well with both characters who have expertise in the religious realm and ones who were medieval peasants before being abducted by Mind-Flayers.
Not knowing things about the world your in isn't a handicap, being forced to make decisions based upon a presupposed information is, and I don't think we've reached that point.
