bought used Yaris 2014 hatchback that needs front bumper, how to DIY

[yaris2014toyota]

I bought a 2014 Yaris Hatchback.

First time Yaris owner.

Seems it was in some sort of accident (see pics).

It's admittedly a risk, but runs well.

It immediately needs a new front bumper. Plus, there were a couple other plastic pieces (one that wrapped around the front right wheel, and another thing that was some sort of bracket on the front right side) that were hanging off the car that I cut with a pair of scissors.

I plan to replace the bumper myself.

My question for you: How do you recommend I go about researching and figuring out what to buy and how to fix it?

Thanks in advance.
