I am working on the same thing myself in conjunction with a youtuber by the name of JustAllinOneResourse
1: Im not sure on this one. It may be a conflict within the 2 mods. I will investigate this one myself
2: Due to Exile having its own loot spawn system, Ravages loot spawn would cause a double loot scenario and would also require you to dive into the Ravage loot scripts to ensure that exile loot will spawn in the crates. I would recommend leaving this option off.
In my version, i just use the ambient ai, ambient zeds, survival module (turn off food/drink requirements and just leave the radiation zones) and the atmosphere module for the color filter and dynamic music.
Hope this helps
