Splash Guards

I have an 08 Jetta SE. I would like to order the splash guards and install them myself on the front and back. On the VW website, it says the mounting hardware is included. Has anyone ever installed these yourself? Is it difficult for someone who is not used to doing many modifications (such as me)? What tools will I need? Lastly, would you recommend the dealer to do the installation? I would prefer to avoid the labor cost. But, I want the installation done correctly too.

Thanks!
Jenny
