As for the ORIGINAL question, it sounds like you have reached the equilibrium point, and you WILL need some more gearing if you want to regain motive power off road. While the 4:11 swap is fairly easy, given the number of used units that are out there, I don't think it is worth the time and effort for the marginal difference it will give you. Besides, if you are happy with your on road speed and performance AND ECONOMY, then don't go there.
Like Mace said, a 203 doubler will get you where you need to be gear-wise, and you can leave your freeway friendly axles alone.
As for the clutch slave dilemma, I noticed this a couple [prolly actually a few] years ago now when working on a customer's '87. I think it was starting in late 85 they went to a different fork and a non adjustable slave. I too was VERY disappointed with the working range of the fork and slave, and had concerns about longevity.
Soooooo, I shortened the rod slightly, put a plate of steel between the bellhousing and the slave which acted as a rest for the fork to come back to, which was at the distance I wanted it to be, then anchored a spring to the fork [which had no provision for hanging a spring] so that the fork would return to my new stop. Clutch engagement was much more acceptable afterwards.
Sorry I didn't take any measurements when I did this. I just made the plate to the length the fork sat at anyways and slowly cut it down until it reached the new resting place.
