That kit appears to be good in the sense it has almost everything you need, and is available with their shocks or a set of Fox 2.0s. I'd opt for the Fox shocks in that kit and yes, I'd get whatever wasn't in the kit that is in fact needed, so I'd purchase a set of new front and rear control arms, extended brake lines, and a set of new front and rear driveshafts as well if I went with this kit specifically. With all the right components you should have no trouble running those 35s.
