Mate, jump onto pradopoint.com. There's a massive knowledge base for modifying Prado's, including heaps of build-ups and how-to guides. You'll get the benefit of learning from all the mistakes everyone else has made, as well as seeing how certain bits of kit look when fitted ie. roof racks, bull bars, wheels, tyres, and suspension. Fair warning though, like MySwag, PradoPoint is addictive and you'll find hour upon hour of you spare time gets chewed up as you scroll through the pages. Good luck!
