Is there a guide on how to replace the hatch garnish for the gen 2 Prius?

I just got my first Prius, I need to replace the hatch garnish.

I found some after market ones that are on eBay and are for the paint code for my car

Is there a guide on how to do this on here?

I also need to replace the front fender on the passenger side. Is there a guide for that as well?

Some info would be great.

Thanks!
