You can disconnect the sway on your stock TJ with just couple tools. If I remember correctly, a T-55 Torx and a 3/4 or 14mm wrench. You'll need some solution to keep connectors up out of the way. I've found a couple of short bungies work, but so will some twine or zip ties.
You will get the better off road ride advertised above, and have a great amount of flex and you're tire will not rub anything unless you've gone to a larger tire than stock without a lift of some type.
If you are planning on going someplace where disconnecting is needed, I recommend taking a compressor and airing the tires down to 10-12 PSI as well. You may be able to go a bit lower, but without seeing what you are running for tires, that is a safe level and will greatly improve your jeep's abilities in the sand/mud/rocks. In some cases, more so that disconnecting the sway bar.
If you plan on disconnecting a lot, buy some quick disco's (you'll know when).
