Gear swap: Anywhere to find instructions/photos?
I did a search....Coulden't really find what I wanted. I'm thinking of going from my stock 2.73's to some nice 4.10's...I'll be getting some sticky tires at the same time. I'm looking for some write-up on how it's done. Setting the spacing etc... Also the motor is making maybe ~190-210hp. Add a 75/100shot of nitrous, plus the tires and 4.10's and will the rear end hold up okay?

Pretty tough to explain the gear set up. You need the pinion set at the specified (by manufacturer) depth. You need the pinion to have a speced amount of preload and you need to have the correct backlash. Richmond gear sells a very good video for about 20 bucks that covers this very well. I recommend it.
