Are there any mods for House Redoran to add to the experience? I know there is one for Telvanni, the Rise of Telvanni, but I was looking for something similar (maybe not as nice) for Redoran.

And other than that, just any mod that has to do with Redoran to enhance the role playing.

The LGNPC series of mods does just that, specifically LGNPC PAX Redoran. Download them from the LGNPC website, found http://lgnpc.org/

Also try Less Generic Nerevarine, Less Generic Tribunal, and Less generic Bloodmoon. All can be found on Planet Elder Scrolls.
