For 'anti-gravity', correct me if I'm wrong, but does an object's gravitational pull also depend on it the speed of it's rotation? ie: If the Earth had the same mass but spun faster, we'd have higher gravity?

Sorry but I'm pretty sure you're wrong. Gravity is just mass and distance, Newton theory anyway. I'll admit to being shakier on Einstinean theory, but I think it's the same there. In fact if the earth spun faster you'd feel less gravity as there'd be a higher centrifugal reaction force offsetting the gravitational pull, so effective gravity would be lower.

But I completely agree with your other point, #2 did sound so much better.
