Ashley,
At the other end of the spectrum, I did everything that Riff Raff hates with no ill effects (if done right). I'm lifted 3" and am running 33x12.50 Wranglers on 15" rims. I have not upgraded anything on my braking system ... yet. I'd like to go with stainless steel lines eventually. I will warn you though that if you lift, you put your CV joints at a harsh angle which will cause early failure of the boots. There is a fix for that though & we can help you with that if you get to that point.
