There are plenty of videos for adding pois to maps I recommend watching them. The quick advice is, make a new game, then go into the world editor (you want the day 1 protection buff for the next part), fly around until you find a spot you want them, I usually drop razor and eve off by roads, I try to follow where Khaine puts the pois so I put the bunker in the winter somewhere, and the research lab in the wasteland somewhere (this is why you want the level/day 1 protection because doing it with radiation sucks). Caitlyn should spawn but I'm not sure, and if anna doesn't spawn just pick a house poi and replace it. Placing pois is a bit glitchy because you will likely have to place it, log out, log in, rotate it, log out then back because of the backwards bug. Ninety percent of the time, even if you place it correctly it will spawn in backwards.
Above is why I've given up and just used Khaine's maps or (yes I also have the compo pak installed) the old compo pak maps. Krunch's maps are a blast but you need the compor pak to play them. I mean one map has an entire wasteland island full of skyscrapers.
