I have seen a few nice quads that have raised stems along with taller bars. Can you give me an idea of how this helps? How high is too high? Are the vibration dampening ones worth it?

Height is your preference. Usually people put low profile bars with tall stems.

Aftermarket steering stems are stronger than stock stems regardless of height.

I personally run Pro Taper ATV High Bend bars with the stock stem and it is right on the money for me.

Most aftermarket stems are of the anti vibe style to reduce fatigue on the rider.
