max altitude deviation before bust?

I thought it was +/- 200 feet before you've violated if you are flying
IFR, but someone just told me it's a 100 feet, which seems a little
steep considering they use 1000 feet separations.

It's +/-100 feet, which is a total range for 200 ft.

I was taught that it was +/- 300 feet and you violated seperation standards
with another IFR target. What is your reference?

It's what I was taught. I think it's also in the PTS for instrument flight
(though I don't have one handy). I haven't found it in a printed reference.

PTS standards for straight and level flight (FAA-S-8081-4C) states
applicant maintains heading within 10 degrees, altitude within 100 feet
and airspeed within 10 knots.

Which really leads me to another question.

If I am assigned an altitude of 5000, does this allow me from 4900 to
5100 or does it mean that I stay within 4950 to 5050? I always took it
as no higher or lower then 50 feet of my assigned altitude.

No, just like when you are cleared on an airway you must maintain the
centerline of the airway.

If you're assigned 5,000 and you're actually at 4,901, you're within 100' of
your assigned altitude.

For a practical exam, I agree with you. The original post asked about
violations in the text. I was thinking enforcement actions, not practical
tests.

Why do you say "a little steep?" Clearly if you understand what is going on
there would not be a question. (assuming US/FAA)

vfr traffic 500 feet above/below
altimeter error allowed - 75 feet.
deviation of 100 feet
deviation of VFR traffic - 100 ft

Add up those errors and you have only 150 ft of separation

Where can you read about the +/- 100 feet, I couldn't find it in the far-aim.
