hard to give a good answer without writing a book.
the more you change at once, the better, as it often puts extra stress on the new components (and you) to take them apart again to change something else. also getting it aligned more than once can be a pain, but if you live around a bunch of potholes, that should be checked yearly anyway.
a good ft end shop could help you if you cant inpect the front end yourself.
upper and lower bushings, all 4 ball joints, and sway bar bushings and links are a start. if you plan on changing the springs or knuckles, they will be off. bumpstops will be easy to get to too. also if you plan on a bigger sway bar, now is the time.
steering linkage parts can be changed without taking anything else apart, but will require an alignment for any changed.
body/frame/core support bushings should be changed all at once if any are bad.
then you have rear leaf springs, pads, eye bushings, and shackles.
not much left as far as suspension and steering after that.
