Yeah, I second that. I'm considering jumping straight from 33s to 35s (after I regear). I'm sitting a little higher (3.5"F/3"R), but still expect to have to do some additional work (pinch welds, cut front bumper, etc).
I jumped from 285/70s to 315/70s, I did the things you mentioned and I'm all good. I do slightly rub on the UCA full lock (JBA). Alignment dialed. If you have 0 offset wheels like I do (or higher offset), be aware.
