First, unless you have an EXTREMELY tall lift, you don't need a super-short SYE. 4-5" of lift does not need one at all, not in the least. The downside to a super-short SYE is that it replaces the speedometer gear assembly with an electronic version. That means you have lost the easy/fast speedometer calibration ability of swapping in a new speedometer gear to compensate for tire size or ratio changes. A super-short SYE instead requires you buy an aftermarket electronic speedometer calibrator like a Truespeed.
There is no real benefit to a super-short for standard size lifts, there is only that drawback I described. Though admittedly if the extra bother and expense of adding an aftermarket electronic speedometer calibrator is no big deal to you, then the super-short SYE would be an ok way to go.
And yes, you will need upper-rear adjustable length control arms to properly set the pinion angle for the CV driveshaft.
