The RE Monotubes ride ok on the street but they are TERRIBLE (!!!!) offroad. I installed a 4.5" RE longarm onto my previous TJ with their Monotubes and I had to slow down to 2-3 mph offroad on dirt roads due to them being unable to maintain control at normal dirt road speeds. Guys in my offroad groups would run off and leave me in the dust while laughing into their CB radios. I'm no fan of the 5100 shocks. From personal experience I'd go with the Rancho RS5000x shocks.
And what tire pressure are you running? Assuming you're running 35's, 24 psi is great for when the TJ is lightly loaded with just you and a passengers. 26 psi is good for when it's fully loaded with people and/or gear. Tire shops routinely overinflate tires, and neither is the tire pressure molded onto the tire's sidewall ever the correct pressure to run. The pressure shown on the sidewall is only the tire's maximum safe tire pressure which would only meant to be used if the tires were forced to carry their maximum possible safe load which would never be done since that leaves no safety margin.
