Where to start with cab patch repair?

[72step]

I am working on a 65 C10 and I've finally finished the metal work on all four fenders. Now I'm ready to move on to the cab which will consist of a driver rocker and cab corner, driver lower kick panel, two small sections of 4"x4" outer floor and the very outer part of the cab supports.

Now where do I start? Cab supports first then move on to the small piece of floor and kick panel then save the rocker and cab corner for last or vice versa? I'm still on the fence about removing the cab. The cab support rust is only the last 2-3" near the inner rocker. Thanks for any advice!
