Its the big ugly weight on the rear end .

Yes, but a fairly cheap battery relocation kit is available at your local Advance Auto or other store.

The "dog-bone" is the weight that is bolted onto the bottom of the differential housing. It is tuned to dampen the vibration frequency of the factory gear set-up. I think they are somewhere between 6-9lbs. Once aftermarket gears have been installed, I don't think it does much good anymore.

OP from what I've researched, every 100lbs you drop is a mpg you gain. Did you notice and increase in mpg?
