What suspension components

I have a 97 tj and would like to put a suspension lift with 33" BFG KO tires.  It's not a daily driver and I don't off road, unless you count the crappy roads we have here in New Orleans. My main concern is safety and stability; my youngs boys love to go for rides. I've read most of the forums here and will take the advice of getting a good kit. But what about other components that don't come in the kit like front and rear trac bars, adjustable control arms, brake lines, and other I may need. Should I buy them also. I only want to go as high as necessary for the 33" and without a body lift.  I want to do it right the first time.  All input/advice is appreciated. thanks  

Sounds to me like you really only need a basic 3-inch lift kit. But look for a kit with progressive rate coils if you can find 'em. You'll want an adjustable front track bar that fits in the factory location (no drop bracket). Don't use a drop pitman arm but replace the factory tie rod assembly with the heavy-duty Currie steering linkage. The factory rear track bar can be retained and fitted with a lift bracket. You may want to look for a weld-on reinforcement for the factory track bar mount on the axle. JKS may have one. I'd opt for a slip-yoke eliminator kit and CV rear driveshaft, but to run it properly you'll need adjustable upper rear control arms. You may want some heavy-duty lower arms but they don't really need to be adjustable.  

Thanks for the info very helpful.  Now I know why JEEP means "Just Empty Every Pocket" but I want to do it only once. Do you have a preference in a basic lift kit? For the rear lower control arms, do I need the longer arms or get a stock length? Thanks again  

Like I said, most basic kits are the same. Look for a kit with progressive rate coils. That's a good sign of a quality kit that will ride decent. I'd also look for some mono-tube shocks. Don't worry about lower arm length. It's not an issue for what you are doing. You can save a little money by sticking with non-adjustable lowers. But option in some adjustable uppers for the rear end for the reason I mentioned.
