Pre-plaster questions: Step tile grout? and Light or no light?

[Tiburon]

I just finished installing the coping (12"x12" silver travertine) which I think turned out great! I also just finished the step-tile (2"x2" glass tile). I am doing the tile and coping myself, and hiring a company to do the plastering.

Question 1: Do I need to grout the step-tiles, or will the plaster fill it in when it gets poured and then wiped off the face.

Question 2: I have the intellibrite pentair LED light. The niche is already in (at the gunite stage) and I have the string ready to pull the wire. Do I install the light fixture itself before the plaster, or wait until the pool is filled up and pull it then? And if you install it before hand, is the lens protected somehow from the plaster?

Thanks, I am also welcome to any and all advice about anything else I need to know in preparation for plaster.

That looks great! LOVE the color of the tile!

Plaster only between the tiles. Grout just does not look as good.

I will call in someone that will know for sure the answer about the light @bdavis I know what I think he will say but want to make sure so will let him answer.

Looking good. I had to go outside and look at mine just now, but mine has grout between the tiles (I think). They also installed the lights before the plaster on mine, with a protective tape over them.

Thanks for the tips. I am getting the basic white smooth plaster so I think it will look good between the step tiles.
