I’ve got a 2001 Jeep Cherokee Sport 4x4, 4.0L, 66,000mi

I'm upgrading my stock Jeep with the following suspension and tires:

BDS SUSPENSIONS

Front 3"Coil Spring

Rear 2.5" Block & Add-a-Leaf

...comes with two front Pro-Ride coil springs that are capable of withstanding full coil bind, transfer case drop, extended sway bar links, and a front track bar relocation bracket to properly center your axle. The rear is lifted with a 5/8" block and a long thin add-a-leaf to add height while not creating a harsh ride. I'll be also be adding a set of sway bar disconnects for better articulation. I think I'm going to run 31" X 10.5R15 Mickey Thompson Baja Radials...

The Jeep is a daily driver, but I'd like for it to be capable off road too. My question is, what do these two options (see below) do and are they worth adding to my kit?

Steering Stabilizer Cylinder ($46.11)

Fixed Lower Control Arms ($170.78)

I would like to write a musical tribute to this wrestler but am lacking information. I have tried several search engines and am still empty handed.
