Well, as is the nature of Fallout, there is always more than one way to negotiate a situation. Taking the agressive route isn't any less of a choice, I'm just saying
Aaaand so we're onto NPCs, my weakest subject
As for NPCs in FO1, they're pretty much flawed when you compare them to NPCs in FO2, where you can give them armour to wear, and they level up with you making them more useful in the late game. All I can suggest is getting your NPCs out of there, I'm not sure what they do if you dismiss them in FO1, they might just stay where you left them. You could try to just give them long range weapons (not including dogmeat, of course) and hope they stay a safe distance from the bursts, beyond that if you can't keep them alive, either let them die or dismiss them and keep them out of trouble.
And you've named the only two NPCs I can remember from FO1
Actually there's that woman in adytum, I think, from the Followers of the Apocalypse? She likes throwing knives though, so I never took her, she sounded like hard work
And lol to Shiny Armour from the Brotherhood
