Five Flagons is in the Bridge district in the city, When you get there, go to your map screen and it should have a marker where exactly it is...
When you get to the grave yard you can refuse the mistresses offer and nothing will happen.. so dun worry!
Umm the familiar thing, i really dun know about that...Do you have Shadowkeeper?
It's an unofficial little program that is an game editor, its wonderful, you can kill your familiar, then use shadowkeeper to add back your Con. point..umm not sure about the web address though...
www.mud-master.com i think
it's very easy to use
