I agree, that's the way to do it. I had to replace my cv's and it was much easier to just do everything at once. I did cv's, Aussie locker, manual hubs, diff drop and cross member drop at the same time.
I can probably help with the IFS kit install instructions. I started writing a for-dummies-like-me version too. I didn't get as many pictures as I should have... make sure you take plenty! I'll send you what I have so far. PM me your email address when you get a chance.
