[Bishop Edward]

1) Not that I can think of off the top of my head...

2) I seriously doubt it but that would be awesome...

3) Unfortunately not an option.

4a) IMHO: Lycanthropes are children of Selune. Even the evil ones, Selune seeks to embrace as her children and give them a chance to turn to the light of Selune and repent their evil ways, etc...

4b) And either way, Malar is an ally of Lolth's, who is an enemy of Shar's as they are rivals for power over the underdark... (back when Lolth was an intermediate deity, Shar didn't mind so much, but now that Lolth is a greater deity, they are considered rivals) - also I found this interesting cross-reference:
"The She-Spider Cult, a Thayan-based sect that tried to link worship of Shar with devotion to Lolth. Opposed in the end by both goddesses, the Cult enjoyed initial success as a secret society operating slaving and drug running operations..."

5) That about covers it...
