Ring and Pinion install price?

I thought that was a little high as that is only the install, they said 3 hrs shop time, no parts included. I would like to do it myself, I need a good dial indicator for the engine build anyway, so I will need? torque wrench inch lbs, what tool sets pinion depth? Found a book for $29, supposed to be for most all rear ends. I can buy the master install kit for around $65-80 depending on brand. Which kit would be the best?
Thanks for all the help Bruce
