Should I upgrade my 2006/6 with touring components?

I recently purchased a set of touring wheels and new tires from a crashed 2009 Prius Touring. I'm wondering if I should contact the seller and get other components? I could possibly get the rear strut/springs and apparently there's some sort of frame brace? I could get the spoiler but it's in bad shape. I already have the sway bar (haven't installed yet), and I've been running 195-6-15s for years and love the handling.
