FYI, the stock springs on XJs are nearly flat. Replacements might be the same. My Jeep sat at exactly the height it was supposed to when my springs were flat. I'd advise you to look into that a little more before you buy new springs expecting much curve. I can't tell you much more about it myself.

I don't remember my 98' sitting so low. My 00' seems extra low in the back. Maybe it's a figment of my imagination.
What about using some medium or heavy duty leaf springs in the rear and standard or medium coils in the front with some good shocks?
I don't know. Any recommendations are welcome. I'm not totally averse to doing a lift but, no more than two inches. If it didn't seem to lean back like it does I'd be fine with it. And I'm not exactly on a budget. Or, I've refused the budget.

I guess I'm just considering my options here. Obviously, my springs are fine. My issues seem to be aesthetic only. That being said, I could certainly live with it, opposed to spending several hundred dollars on springs and shocks.

What is the best way to track down a short? My jeep has been shocking me whenever I get out of the vehicle. But I figured if it still starts why look for the short?! But guess what. didn't start this morn. Dead as a door nail, so we jumped it, dove it for 30min 4 hours after that, dead as a door nail... So what's the problem or what's the easiest way to track down a short.

You can go up 1" in height very easily without changing anything else. From the factory this was part of the UpCountry suspension group. There are also companies specializing in small lifts like Old Man Emu. OME ride great but is very expensive (reverse pricing for that Australian disadvantage maybe?)
Staying cheap though, your front coils are probably fine, so I'd go with MD or HD leafs in the back and new shocks all around. XJs can do a lot of work and I don't think SD springs really cut it.
Then put the rest of your money elsewhere, like into the cooling system, or keeping the wife happy. Lol

Yup, once it warms up though. Here's an example of what you're looking for
That's not from a Jeep - because I'm lazy - but that demonstrates a mostly working cat. The signal from upstream represents the computer adjusting fuel to hit the 14.7:1 AFR. Obviously not a, er, fine work of art since it's constantly turning the amount of fuel up and down. Downstream should be a steady signal once warmed up as the catalytic converter smooths out all the crap. Compared to an XJ that graph looks like it's reading on the rich side with a higher downstream voltage. However, STFT and LTFT will tell you if it's constantly adding a ton of fuel or trying to lean it, or spazzing out and adjusting STFT wildly (points to a vac leak or some kind of other fail)

The upstream sensor came out with white deposits, which I've read (I believe from CCken?) can mean coolant leaking into the cylinders... but I run cool-ish and don't leak coolant.
Next course of action... double check the wiring for the upstream o2, test cat (point an IR thermometer at it, output should be ~100* hotter than input?), and check for vacuum leaks?
Graph sucks, I'll see if I can get anything better... but it definitely shows how my downstream voltages are all over the place...

thoughts on this bumper?

looks good and ties into frame.
