rust fix - floor corners

[johnwaynejeep]

I stripped my cab floor today and found a fair amount of rust on the passenger side. Does anyone have tips on how to fix it.

I looked up replacement components from auto metal direct and auto body specialties and I'm planning on cutting out the rot and welding in new panels. I wanted to get opinions on whether there was a better way and I want to make sure I'm getting all the right panels.

I ordered a kick panel, floor pan and outer rocker, is there anything else I should order?

Thanks in advance
