Re: Everyman/Hidden Lands/Vibora Bay & more.
Everyman is what we call a "normals book." It presents a whole slew of interesting normals for use as NPCs in a Champions game. It's not about playing normals; it's more like CKC, but with normals instead of villains.
Hidden Lands covers mainly Atlantis, the Empyreans, and Lemuria, plus a few more minor places. I don't think it's as freaky as you're envisioning it being, but I may be misreading you. 
As for Vibora Bay, I'm not sufficiently familiar with DC's London to answer the question. It's our sort of weird/outre/mystic city for Champions, as opposed to the more high-tech, mainstream Millennium City. The influences cited by Darren are James Robinson and Tony Harris, Alan Moore, Jamie Delano, Steve Gerber, Len Wein, and Bernie Wrightson.
What do you mean by "high-tech fantasy setting"? Do you mean an urban fantasy sort of thing -- magic in the modern day? Or do you mean a High Fantasy world where magic has taken the place of tech and you have magic flying cars and such? Or something else?
