Front Bumper Replacement instructions?

I ordered a prepainted front bumper and the two missing left/right fog light covers to repair our 08 prius.

I found a few threads saying it's not hard to diy, but no actual instructions or list of needed tools.

This video seems helpful, but what is that wrench tool he is using at 5:36? link doesnt seem to be working, its "Remove Front Prius Bumper JB WELD repair" on youtube.

 

I had a vague idea it was a socket wrench. I have been able to service non-user serviceable items like home appliances and supposedly non-openable ultrabooks, so this seems within my abilities

But I'm not sure what liners/underside covers I need, what source is reliable, or whether I really need them. Even if I take it in to be fixed, I presume I will save some markup on the parts.

It's been serviced incl at a Toyota Dealership, since accident, they said the damage was just cosmetic and took care of other standard work at the time, I think cooling tank and belt. Thanks btw to this forum I was able to confirm they were playing straight with us.

Family member who holds title and had the collision (i think she said slow moving against some stones in her driveway) has been procrastinating the body work.

 

Pretty sure grille comes in 3 parts for both the standard and fog light models, center is same for both but the left/right covers are different:

Non-fog light passenger side grille cover:

Passenger side grille cover with hole for fog lights:

Grille center:

I need to know, though, exactly which and how many liners/splash guards I need, and whether I will need new fastners.
I think this one is busted, "Engine Splash Shield Under Cover Plastic, 429-44102-03 TO1228141 5144747010," but someone said they are optional and reduce airflow? This is the part on the underside that connects directly to the front bumper cover, right, or is there another black plastic piece on front?

Then this "Left Fender Liner Splash Shield Assembly Front Driver Side LH, TO1250116 OEM 5387647020" appears to be busted too:


So between those two (which I dont know where to source, Amazon reviews for those liners are bad), and the bumper, maybe this is not a job for diy without previous auto experience? Or do I not need the splash guard anyway?

 

Thanks. Are there any recommended sources/vendors around here? Amazon had many options for the grilles but not the splash guard or driver/passenger fender liner splash gaurds.

Also are there any online sources or pdf's of the relevant parts of the service manual?

I need to determine which fasteners i need, whether i need the fastner remover tool, etc.

 

Thank you for that. The diagrams are useful.

I took another look at the vehicle, I know I need the valence/spoiler, engine undercover, and the bolt and grommet that goes up through the valence and engine cover corner- in addition to the bumper and grill parts which have arrived already. I think I can reuse all the rest of the clips, but we'll see.

If it weren't winter and/or there was an indoor garage, I'd pick up a socket wrench set and try this myself. Video looks relatively straightforward. But as it is 25F out, we'll probably use a pro.
