Dart front disk service- any tips?? Basic questions...

Hey, guys! Next project is to refresh the stock front disk brakes on my 'Sport.

I'm desperately hoping that the original calipers can be saved...what are the odds?

Sitting on the bench, I have fresh rotors, pads, flexible lines (the ones on the car are almost certainly the originals...look scary)...what else should I replace while I'm at it?

When everything is apart, is it typically a good idea to repack the wheel bearings? Do I need to worry about "lip seals"? If the master cylinder isn't leaking, can I assume that it's ok?

What kind of fluid do you guys suggest?

I have a very generic Valiant/Dart shop manual that isn't helping much so any tips or experiences would be appreciated!!
