Unless the drums are out-of-round, why would you need to replace them? Drums can be turned if needed.
Brake shoes are only $30-ish, and again, unless they are oil-soaked or down to the rivets, they should work just fine.
You might need to go through them, make sure the wheel cylinder is good(or replace it), then adjust the star-wheel while spinning the tire by hand and occasionally pumping the brakes until you have something that doesn't drag without pressing on the brakes, but stops nicely with the pedal.
That being said, while I haven't had much trouble adjusting them myself, I once took it to a shop for an axle seal and pads. They screwed up the adjustment royally - first time, no E-brake; second time they tightened it up so far that it was smoking within 3 miles.
(I just loosened it up a bit in a parking lot, then fixed the e-brake adjustment later)
I've had more trouble with front disk brakes sticking on me than rear ones, except for when it was well below freezing and the e-brake cable didn't want to move on one side and stayed stuck on until I found enough traction to break it loose...
