I have the turner kit.... If you have ever worked on a car before its very easy. The only trouble area is getting the Alt. pulley off (its free spinning and torqued on pretty tight.
The turner instructions are very straight forward. (Im pretty sure that they included the torque specs of the pulleys... all of them except the alt is <25 so make sure you find the appropriate torque wrench if you are inclined to torque them to spec.
I also printed a copy of one of the fan belt removal DIYs from this site so I had the correct size allen wrenchs around when I did it.

Since your pulling all the stuff out, I would also recommend doing the fan delete mod while your at it. I was very pleased with the TMS & fan delete.
