Michael,
Sorry I didn't see this post until last week. It is fairly straight forward with the right tools and patience. I would only look to changing the sprockets if it had damaged teeth. Mine showed almost no wear and I know I saw some pictures of broken teeth, I think that is due to the pads or chain being worn really bad. Let me know if your planning on tackling this. I may be doing it again on my high mileage 93 since I see no history of it being done (and it has a lot of history!)
Cheers
