About Rias' parents: My bad, I was thinking about the anime version. If Lord Gremory was there, of course Venelana was too. But TNK had no reason to animate them (I was actually really surprised they even added a rough design of Sairaorg in there) even as promotional material as they never predicted the sales it had and none of them even appear until S3.

About the marriage: I was referring to those watching the anime and the reason the battle felt more intense. If anything, in DxD New the Kokabiel match sorta seemed like a joke; just there for the plot and the major revelations following it. At least until Vali came in.
