Is it your daily driver? If so have a shop do it. They will be able to rebuild it faster and be sure (hopefully) that it is done right the first time.
If its a toy, do it your self. It will take longer but it will be an excelent learning experiance. Be sure to pick up a manual and make sure you have a good torque wrench. Just take your time, double check everything, and you will learn a ton about engines!

I completely agree. I re-built my first engine when I was 15. I got the tools and the parts along with the Chilton's manual and went to town. I ended up having a shop go over it because like rngprerunner said, "have a good torque wrench; I tightened everything so tight that the car wouldn't stay lit unless I put my foot on the gas. It was wound a little too tight. The shop loosened things up and torqued it to spec and everything was good.

SAE correction is just for the weather -- temperature and humidity. It usually doesn't end up making a difference of more than a few horsepower in either direction, but it is a way of ensuring a greater degree of apples-to-apples comparison. If one guy tests his car in 90-degree weather, and another tests his car on a cool summer morning, you're going to see a noticeable power difference -- cool air is denser, and makes more power. Most dyno places provide SAE-corrected numbers -- and who knows, the graph you posted might already be corrected. Your shop would know.
