questions about sacrifice

By PlasTicX, in Warhammer 40,000: Conquest - Rules Questions

Hi,

I had 2 questions about sacrifice.

1) I have Captain Markis, Coteaz and other AM unit on a planet. Can I sacrifice one unit to trigger both actions on Captain and Coteaz, or i have to sacrifice two units - one to trigger Captain's action and one for warlord.

2) I have Coteaz, his Henchmen, and Guardsman token on planet. Me and my opponent, don't have any ranged units. I use Preemtive barrage, so my units are ranged. I attack with token, then sacrifice token, attack with warlord, attack with Henchmen. Now I sacrifice Henchmen to ready warlord and give him +3ATK, is warlord ranged and is still ranged skirmish?
