Help! Removing fender flares and replacing with Pocket Flares

I will replace my fender flares om my 2006 Taco with True Edge Rivets pocket flares.
I hear the hardware needs to be replaced wih stainless screws to avoid rust. But the guy didn't tell me what screws etc needs teplacing. Taking out the plastic clips are hard and will break. Then you have to remove part of the bumper skin to get to some other clips for removal of the small front fender flares piece.
This does not seem easy to do like everyone says. Plus I want to add mudflaps which does not seem easy to do now that the new fender flares sticks out further than stock one.

Is there any easy tried and proven install method that works?

Thanks.
