As for the glow: The promo image gets it's effect from more than just ambient, but ambient is likely used: In the body-image, you can see that there is a light-source somewhere on the right with the same turquoise color as the lines of the suit have (right illustration); there is another one (blue) on the left. You could try colored spotlights with shadows disabled.

And if i look closely at the glow of the helmet (left illustration) i would say that the corona of the glowing parts was added by compositing - it looks like a blur of the ambient channel that extends beyond the actual geometry. You will not get that easily directly out of Poser.
