About your dialog-camera problem. That's not hardcoded, but the files you have to edit are not unpacked from the archives in the patch, or in Camarilla or TFN mod. I don't know about Clan Quest or Comp mod.
You'd have to unpack the subdirectory \vampire\vdata\camerashots\ and edit the files dialogdefault.txt and dialogdefaultwoman.txt That should cover for most dialogs. Sorry can't help you any further, because I have only made a few tests with these files myself.

For the corpses, I don't know what keeps or removes them from the map.
