Remember you're betting your life on the brakes every time you step on the pedal. I'd reccomend replacing the wheel cylinders as a matter of cheap insurance rather than trying to rebuild them, especially if you can find original-equipment items, not imported ones. Old wheel cylinders have a chronic problem with rust pitting, and just replacing the rubber parts won't solve a leak on occasion. Ditto on the axle seals - - - -it's a reelatively simple procedure to pull the rear end cover, remove the axles, and replace the axle seals- - -low cost insurance you don't spoil the new brakes with rear end lube leaks. Do it once, do it right, and drive on!
