I bought a new truck! Rust repair questions

[ZombieWeinerDog]

i got myself a nice 67 shortbed for a good price. needs new rockers. bottom of the pass. door needs replacing and the drip rails are nasty. how can i repair the rails? i want to keep the patina, or strip the whole thing and paint it flat black. i tried to get the worst spots in the pictures.

has a nice 355 that needs to be re-assembled, ac, intermittent wipers, really nice interior too. it was restored in 92. it really needs it again though. this will be my daily spring, summer, fall (no snow) driver.
