If you want oem fitment, go to your local parts store and get replacement parts. You don't need anything high dollar for an oem type setup. I would however recommend some lift. If you're wanting to play on the trails and go off roading you will want some ground clearance. Some people will argue that lower is better, higher is better... it's all a matter of personal preference. But just about everyone who has an off roader will have at least some lift. 1-2" with slightly over sized tires would be a good starter.
Larger tires also help you roll over objects easier. And you can still fit 33s with a stock suspension. I would however, heavily invest in some armor.
As for the original question, brace your idler arm, besides that, as long as you grease everything regularly , should be fine.
Also might want to look into a IFS truss.
