Personally, I have not and a lot of the EU. The comics have been both expensive and hard to come by where I live, and the writing of the novels ranges from excruciating to passable. As for the prequels (including the Clone Wars movie) they had some good bits, but also a lot of drek. I haven't seen the Clone Wars TV show, but I remember the Ewok/Droids show....
I don't see any issue at all with re-writing Star Wars "history" to suit ones own tastes. Edge of the Empire is a role playing game, a hobby that is meant to be creative. Look to Star Wars as inspiration, not a creative straight jacket.
And, yes, this does mean if the EU is what inspires you then you should use that as the background for your game.
The problem comes when you wind up with players walking away from your table because they don't share your bizarre take on the SW universe.
And for what it's worth, the Clone Wars series is pretty decent.
