I'm clueless about discus breeders, although they will feature with me at a later date if all goes to plan 8)
If I was you, I'd plant heavily, even with low foreground plants so gravel cleaning isn't needed, the plants will use the fish waste as fertilizer. But your way can work too.
I love the BN's, I have more than 50 of them. Really cool fish IME.
As for the tank, I believe it's bow front not bay front
