From what I've seen first hand with a 2" spring or spacer lift, if you undo the parking brake cable from the rear mounting points on the rear of the frame, you will be fine.
As far as the brake lines are concerned, either get a longer replacement from Calmini, or add on to it using a VW Bug or van short hose from a local VW parts place, very cheap. The front, if you have a problem with front hose length, put a left front hose on the right, and re-route the left to about the same level, problem solved.
The droop issue can be addressed by flipping the strut spacer, and having a 1" spacer made for the top of that. The rear, you need to put longer shocks on it, plain and simple.
From what I've seen with installing the Calmini 3" and using other routes to accomplish 3" of lift, the steering can be adjusted very easily, just a toe adjustment. The Calmini also has a camber fix in the control arms. But that one you could fix with eccentric bolts.
