Cab repair question

[85sierraclassic]

Ok getting ready to have some repair work done on my cab. but have a few questions about the floor pans,
first off the drivers side inner and outer rockers are in good shape just little bit of rust in cab corner.
I need to replace the floor pan on the drivers side for sure. it's been hashed from years of collected dirt and mud under the mat and starting to get weak in a couple spots.
I'm not sure on repair panels what I need....would like to keep from having to completely redo the rockers too. Different places list parts and I'm not sure what would be best . Here's what I'm looking at ..... Oh and floor braces are solid also just part of the floor is bad.
Which of these would work best, without to much other work? Thanks!
