Cab patch panels order of operations?

[CivilEGR]

First time doing any bodywork ever, so expect a bunch of questions in the near future.

I've pulled what was left of the outer rocker panel off and I'm working my way forward. It looks like I need to replace the whole lower A pillar, but I also need to replace the inner toe kick area, the inner rocker, some of the floor, and most importantly the cab mount.

Should I just cut everything out and start building back? Or should I go in a certain order?
