From the auction, looks like it is being sold by RC.  I like RC, haven't owned a RC kit but I've seen many of them on the trail and they work very well.  Looks like they've got a great guarantee.  
That kit should be all you need, but I'd take a look at how centered the front axle is, side to side, once the kit is installed.  If needed, you can redrill the lower hole for the front track bar a little to the driver's side to recenter the axle.
