You should use a sealer before applying the toner.

There are several ways to spray the dark color. But whatever you do use the ultra-classic dye-based toners, as they will pass the wood grain better.

I like to spray the entire set with the lighter color toner, then spray several light coats of the darker toner until I am satisfied with how it looks.

For your set I would recommend universal walnut for the darker portions of the cabinet. You are not after an opaque finish, but rather one that looks very dark in dimmer light but allows you to see the wood grain in bright light.

VanDyke walnut is ok too, but will lend a "violet" tone when under bright light. The universal walnut is more brown in nature.
