Basically...yes it's a matter of swapping the ring and pinion out. I'll let someone else take care of answering your question as to *if* a master install kit is required. I'm going that route because basically you're rebuilding the axle(new bearings, shims, ring, pinion, fluid and the like)...and my axle has 130k on it...why not you know?
The notched crosspin is talking about some ratios require that becaise of the size of the ring gear. You can reuse your stock one with grinding of the stock crosspin to clear the ring gear..or you can get an already notched crosspin if you wish to not mod your stock one. At least that's how i understand it. I'm a noob in this whole gearing/gear swap specifics dept. But i'm learning.
