you have one extra item
You don't need both the panhard drop bracket and the adjustable panhard bar. The bracket is for folks that don't want to spend $200 more for the fully adjustable bar. Using both at once is not better. Save yourself $50 and skip the bracket.
As OkiSurf1996 mentioned though, you might want to add a drop kit for the front differential (at Toytec it's part TAC-DR).
