Good questions. Good camping skills are key to good backpack hunting.
When I camp, I am in close proximity to my glassing spot, which is usually in close proximity to where I am going to kill something. It is key to be at where you want to glass before first light, so unless you want to hoof a mile or so in the dark via headlamp blowing everything out, camp close to your glassing spot and very quietly slip into position without waving your light around. Darkness will conceal your movement. Then, don't move for a few hours as it gets light and good things will happen for you. Know the forecast and know what direction the wind is going to be blowing from. Camp and glass accordingly. Never skyline.
