It's a 4.0L and it doesn't have power steering? That's a bit strange unless the PO did some work on it. You'll need the steering box, hoses, and the pump. I believe the pump on the ZJ has the combined pump/reservoir so you may need to see if it will interfere with your airbox.
I would imagine getting YJ bracketery would be a good start, or something. Maybe like Louie says some hoses and a few nuts and bolts to put it all together would be plus. How about a belt ? No not for your pants but for the accessory drive.
In all seriousness, you have almost 2000 posts and your asking newbie questions like this ? C`mon share your knowledge with others, or something.
It is really not a difficult project. At least it wasn't for me with my '94 2.5L. The pump mount and alignment is the hardest part. I'm not a auto mechanic, so if I can do it, so could you. Louie already posted the link to my thread when I did it seven years ago.
If you have any questions, feel free to PM me. I'll do my best to help.

got a pump and box coming off a 92YJ. from what i can see the mounts are identical; i won't know until bolt it up. so just gonna start playing with stuff until it works.
should be this weekend. i have lots of time before the rest of my laundry list of parts i ordered come in
ok. quick update cause I deleted the long winded post I did before.
VERY easy swap. you need: power steering pump, steering box and power steering bracket from a YJ with power steering. then its BOLT IN. biggest issue was connecting the steering shaft. easy easy.
so ya. converting non power steering/ manual steering to power steering is easy if you buy the right parts...... I do not have a junkyard solution; but with stock YJ parts its all plug and play
