Help identifying Star Wars set from troopers and white pieces My nephew handed down his LEGO pieces to my son. Most of them seem to be Star Wars. I need help to identifying them so I can download instructions.

Appreciate your help!
Seems to be mostly from one set with a mixture of Minifigs and accessories.

Some Minifigs and accessories. 

Set #8084-1 Snowtrooper Battle Pack. (Referencing your picture, some of your Minifigs come from this set.)



Headgear: Part 61182 Minifigure, Headgear Helmet SW Rebel Scout Trooper. ( Comes with a black visor shown in your picture.  Headgear used on the figure directly below, which is NOT in your picture.)
