Ok. Dont be intimidated by the idea of diy service in this area! There are loads of how to videos on youtube.
There are a few other tools needed to do that timing belt job. But they are not super expensive. For instance, the serpentine belt is a stretchy type and needs a tool to smoothly guide the old belt off the pulleys and the new belt onto the pulleys.
First image is of the Dayco kit for the belt.
The second image is of a deluxe kit for service of the timing belt. I chose this image that described each tools purpose. You can easily get each of them alone or you probably can rent them from some of the parts stores that offer tool rental.
