Don't do the shackles without the leafs. You have to disconnect the leafs to do the shackles...and then it is just two more bolts and you put the new leafs back on. You could conceivably do the control arms, although they'd be the wrong length and that might cause complication.
Here is what you need to do:
1) Start on Friday afternoon so you have all weekend;
2) Get a friend to help you. Even if neither of you know a thing about suspensions, this is nothing more than nuts, bolts, and leverage. A second set of hands is invaluable;
3) Make sure you have the right tools:
This includes all of the necessary sockets and wrenches and a breaker bar (just a 2' piece of plumbing tube from Home Depot that will fit over your socket handle is plenty);
A pickle fork for the trackbar tierod end (assuming you are replacing the trackbar);
A rubber mallet for whacking bolts back into mounts when they are close but not quite sliding in (this is invaluable...an absolute must-have);
A hand winch (come-along) is absolutely invaluable for lining up the axles when you are doing control arms and the leaf springs. You can literally spend hours trying to get bolts that have a preload out of their mounts (and longer trying to get them back in), and this can be done in minutes with almost no exertion with a hand winch.
Get a floor jack and four good jackstands...don't try to do this with the little bottle jack that came with your Jeep...it is dangerous and will take forever.
Be willing to apply leverage to do the coil springs. A 4' long breaker bar (or a long crowbar) does wonders for popping coils over stubborn axle mounts (both for removal and installation). You aren't going to break anything...but if you try to be delicate with it the coils can become a real nightmare.
If you have the right tools, this is an easy one day job with a friend (and if you have the hand winch it is an easy one day for just you). If you try it by yourself without the right tools...then you might want to reserve a rental car (Enterprise will pick you up
) in advance.
