Duster Rear shocks too short w/XHD Leaf

Let me ask a couple questions here if I may.
If the shock is too short by an inch or so, I agree that once the car is ready to roll, everything mounted, gas etc. that it will most likely ride and drive fine. Probably never see the shock fully extended on the road. What about when he rolls it in for an oil change or tires? If it is lifted by the body, that would place the entire weight of the rear axle being held "up" by the shock - those two upper shock bolts to be exact. Would you see a problem with this?
My second question is in regards to the rear brake hose. With the extra lift, any danger of having this hose too short?

My questions come from having done two mods to my car. I've added a rear leaf, not for extra height but for the extra stiffness for an M body rear axle. I did get a little extra height in the bargain, though.
Second, I placed a 1/2" spacer in front of the front hanger. Doing this has centered those big 15's in the wheel well near about perfect.
I did notice when the shocks are hooked up they do not allow the rear axle to drop as far as when they are hooked up when lifting the body.
