Depends, how much money do you have?
If you wheel it hard you'll find all sorts of weak points with the factory parts. Is this going to be a brand new jeep?
The most simple thing would be to order a full synergy suspension bolt kit. New bolts, washers and nuts for the front and rear track bars, upper and lower control arms. The stock bolts are undersized and threaded the full length through the bushings. This buggers up the sleeves in the bushings and creates slop. The synergy bolts will be the proper size and shouldered. Be sure you have a quality torque wrench of course. It makes sense to do this with the initial install.
I would also recommend the geometry correction brackets from AEV ($100 or so) which will reduce brake dive and correct caster back to stock numbers. Do not use cam bolts. If you don't like the brackets, consider adjustable front lower control arms.
Next, a quality adjustable front track bar. This will allow you to center the front axle, and a firmer track bar will improve steering a huge amount. The stock bar bends and flexes and causes indirect steering and drift, more pronounced with big heavy tires.
Later on you'll see a big improvement upgrading the tie rod, drag link and ball joints as the stock parts are all soft and 35s take their toll.
If you wheel it, I would strongly recommend front axle sleeves and C gussets to keep it from bending. This is a good time to replace the ball joints as well.
I could go on and on but I'll refer to the first question.
Either way, the bolt kit when you install the lift. Geometry brackets too if you do them. The track bar is optional and can be done later but it is a major improvement.
