You probably won\'t need to replace the shocks. Might as well wait and see if you net any lift before buying new shocks since they\'re so easy to switch out.
Don\'t bother with new brake lines till you get about 3\" of lift. Then you use YJ brake lines. Less lift than that, just drill a new hole and move down the bracket that mounts to the body and straighten the metal line coming down from the engine bay.
I don\'t know about Rubicon coils adding lift but ZJ V8 coils and F150 coils will.
A Dakota/S10 add a leaf will match it in the back.
