What changes ? Just .75" spacers on top of the front coils? Or adjustable trackbars as well? And new driveshafts? 
The steering is flighty/floaty? When you hit a bump it darts to one side?
The last two sentences of the first reply you got is likely what you are feeling... Lifting causes the pinions to tilt up, which lowers the caster. Low caster causes flighty steering.
If you want to raise the caster, you need to lower the pinion. The options are cam bolts, control arm drop brackets, new fixed length control arms, new adjustable control arms. Prices and opinions vary on each option, so do some research. (aev and rancho drop brackets are getting more and more popular, wouldn't be a bad idea to search and read through a few of the threads)
my Jeep feels like it's all over the road at highway speeds. What causes this and what is the solution.

I don't think you have gone high enough to need new Drive shafts.
I have a 4 inch lift on 35's and stock drive shafts...of course I am a JKU...but I know plenty of people that did not upgrade unto 4 inch lifts even on a 2 dr.
hope that helps.
