"How long do you brew this "Strong, smoky, black; liquid campfire"? And is brewing just throwing them in boiling water, or do you let the water boil, throw in the tea and then remove from heat source?"
I take the pot off the stove just before boil to save the fuel required for phase change from liquid to vapor, toss in my preferred amount of tea, cover and let steep for about 3-5 minutes, depending on how strong I want it on any particular occasion. Lapsong Souchong has a very pronounced flavor, and you'll have to experiment a bit with the amount of tea and length of steeping to get it just right for your taste. I usually brew with a pint of water and hand measure what is probably 1 1/2-2 tsp of leaves. Sort of like old time house wives would use a pinch of this and a handful of that.
On a more romantic note, the best Lapsong Souchong I have ever tasted was made with water heated over a slightly smoky wood fire back in the day, after a meal of fried trout and crispy potato pancakes fried in fish drippings. Sigh. ;)
