The series of jobs which starts with 'find info on Fang from the diggers' (or something like it), then continues to a Dark Valley entrance, where I was to help a Stalker fight off dogs.
He died in the fight, then I got a new mission and a PDA message attributing it to Wild Napr.
Have I gone too far at this point? I still want to avoid hostilities with the Bandits, but had no option to decline the mission.
No, that mission is part of the main story thread. Wild Napr can give you some missions through a dialogue choice that begin with finding a PDA that holds coordinates to a weapon cache and ends with a group of Stalkers freeing their captured friends from the Concentration Camp. Once the guards are killed and the Stalkers are freed the Bandits all automatically turn hostile no matter what, I once even had other Stalkers complete it for me when I wasn't near the camp and the Bandits still turned to instant enemies despite having a mostly full positive relation bar just before. If you simply avoid doing those you should mostly be fine with the Bandits.
Later on in Agroprom you'll encounter some missions that can lower your status with the Bandits as well, but as long as you don't let the relation bar dip into enemy levels you can raise it again by helping them out around the Garbage.
---QUOTATION--- Saw the 'Collect your reward' for Hound was 50K ru and a FN2000, so I hoofed it to Swamps. ---END QUOTATION---
That reward is certainly not part of the vanilla game, it's much too big and will spoil the player.
Went to the technician to see about upgrades for the new rifle and got the 'Are you sure you want to change locations?' window halfway up the stairs. ---END QUOTATION---
Sounds like a mod bug. I've never experienced anything like that in vanilla (except once in my first unpatched game, where I was somehow sent from Red Forest directly to Limansk and missed all the gameplay in between).
Scouted the route through Limansk and that was brutal!
My armor is shot and I have very little ammo, and we go straight into the deserted hospital?
I have an RPG and 1 round left. Saving it for the machine gunner.
Another thing: when fighting in deserted hospital, the light background would cause me to lose sight of the cross-hairs. I placed a piece of clear tape on my screen over the cross-hairs and drew one with a thin back Sharpie. Boom.

Sounds like my first playthrough, at the time I hadn't yet learned how to upgrade armor so I was wearing something like shreds of a leather jacket in the hospital. I learned much later that the CS squad leader in the hospital can repair equipment.
