I'm installing my front adj sway bar end links right now. The front wheels are both on ramps.

For zero preload, my passenger side is almost full length and my driver side one is almost down to the shortest adjustment. This is with noone in the car. Is this ok?

 

The bar isn't bent, is it? I'd try taking her off the ramps, roll her around a bit, then check again. You might have other issues with the suspension if you are still that far off....

Check the height/condition of your mounting brackets (bar-to-frame) as well.

 

For zero preload I'm pretty sure you're supposed to put all four wheels on ramps, or whatever you choose, as only the front being on ramps would shift the weight to the rear.

 

you might be twisting hte car a bit with only two on ramps.
ideally you want to connect them on an alignment rack.
