Ha on your cool user name... that MOS was called "11-Bush" when I was in many years ago.
Your shaking is very likely the all-too-common Death Wobble. That is normally triggered by an out of balance tire or bump in the road & allowed to develop into full-blown Death Wobble by something loose in the front-end like a bad ball joint, bad bushing, etc.
The first thing I'd do is have all your tires very carefully balanced so they are perfectly
balanced. The "good enough" that some tire shops balance tires to is not good enough where a Jeep and Death Wobble is concerned.
Then, or maybe even now, I'd grab someone to help you look to see if something is loose/moving that shouldn't be. With the tires on the ground, have a helper turn the steering wheel repeatedly back & forth while you look at all of the front-end components for unwanted side-to-side movement... particularly the passenger-side track bar mount, control arms, tie-rod ends, etc. Caution that there is supposed to be normal 'rotational' movement for the tie rod and drag link since they are mounted on ball joints... but they should not have any side-to-side slop at all.
So Death Wobble is normally a combination of things... typically out of balance tires combined with something loose like a loose passenger-side track bar mount which should have zero movement.
Power-wise, yep that 2.5L engine is no powerhouse... just make sure you're downshifting early enough for hills.
Finally, make sure your toe-in setting is proper. Improper toe-in can encourage Death Wobble. The following link will tell you how to set your own toe-in. It also includes a cool photo of the front end that will identify the above mentioned items like the track bar.

Good luck with the Death Wobble... it can be frustrating and sometimes hard to cure but it is curable with a little effort.
