If the events of Star Wars happened a long time ago in a galaxy far, far away, does that mean if we had a good enough telescope, that we could watch it be played out before our very eyes?

Well yes, we see distant objects delayed by finite speed of light and thus substantial travel time - but you have to remember the limit of resolution.  At visible wavelength and in the nearest galaxy you would need a light gathering surface of 10km diameter just to be able to resolve two objects at 96 million miles apart!  To get resolution of a millimetre you would need a telescope far bigger than the solar system.

so we'd need some sort of giant, interstellar moon-sized space station?...

Can you increase the resolution by using multiple small telescopes, each widely spaced apart?  For example scattering a million large optical telescopes around the Oort cloud?

Yes - an astronomical interferometer.

Following up Bizerl's suggestion of a moon sized space station - was its destruction an inside job?http://www.youtube.com/watch?v=2dvv-Yib1Xg
