Since it is now known that the observer is part of ANY observable event, don't we need to redo oh so many so called factual observations?
Is it even possible to observe something without the observer changing the outcome?

It is important to realize that the effects of observing are very, very small, and are typically only significant at the quantum level. We are usually talking about the effects photons on other subatomic particles. There are a couple of schools of thought resutling from Quantum Mechanics that hint at deeper, macroscopic effects, that is effects for large objects, but this stuff is still highly theoretical and but one or two interpretations that compete with about a dozen other theories.

It is true that no observation of any kind can be made with any amount of accuracy, but for a more important reason than the effets of that observation.
We forget sometimes that we view the world with an imperfect tool, and will never even hope to fully comprehend anything we observe. Pidgeons can see geometrical patterns in light, and dolphins can change the frequency of their communications. Face it, we are not all knowing, and can never hope to be.

[SOLVED] Observing changes the outcome.. how can we observe?
The universe evolved just fine without any observers [er, us in particular] for a very long time. The universe has also been kind enough to let us watch the video of how it all happened. The fact it is behaving in exactly the same way now as it did long before we even existed, suggests the observer effect is temporal, at best.
