I need to replace the wheel cylinders and shoes.  Any advice on the process?

A brake spring tool is very handy to have, be very careful removing the rather thin drums.

Otherwise it's a straightforward process.

I also recommend using Permatex Brake Lube during reassembly.

Also, if you're interested it might be a good time to consider switching over to DOT5 brake fluid. Doesn't absorb water and won't harm paint.

DOT5 as you say will not mix with moisture and THERE is where the problem lies.
 As the water  (Moisture) in the system separates from the brake fluid it will go to the bottom, settling in the calipers or wheel cylinders, when you have to apply the brakes hard, the moisture will heat up, turn into vapor and your brakes will begging to fade, the harder you apply the brakes, the more they will fade.
 In a race application or where the fluid is changed regularly there will be no problem because very little or no moisture will be present in the brake system, but for the rest of us DOT 4 is more than enough and if you can find DOT 4 Synthetic, better for you.

As long as you correctly clean the system out before putting DOT5 in then you're fine. There is no water in the lines, etc.

I've been converting all my cars when they get their brakes gone through. That's 5 cars now that get regularly driven and no problems.

As you said it, as long as you get no moisture in the system.
 We were working in STS vans transporting the elderly and the infirm and we used DOT5 but since the previous mechanics did not flush the system before, there was moisture in the brake lines, we had nothing but trouble in the more than one hundred STS vans that the Miami-Dade County had, we went back to DOT4 and all is ok til now.
 I have a Volkswagen super beetle 71' which is one of my toys and the brake system is filled with DOT5, all the fluids are synthetic and get changed every year along with the brake fluid, never had a problem, but humans, been the way we are......

BTW, make sure you clarify WHERE in the brake system is the Permatex Brake Lube is to be used, because humans, been the way we are......

The lube is for the rubber bits on the wheel cylinder during reassembly.

I have been using EIS Stock#AF100 Hydraulic Brake Cylinder and Caliper Assembly Fluid for about 25 years now with great results: I guess one is just as good as the other, just a matter of taste.

That's good too.

Many people were never taught to use the stuff when assembling brakes. That was my main reason for pointing out the Permatex as it's available at most local FLAPs.

assembling it with petroleum based products like engine assembly lube, lubriplate white grease, red grease, etc have made many owners come to me with leaking and other problems.
 the use of BRAKE CALIPER AND WHEEL CYLINDER assembly lube  (Of any reputable brand)  will go a long way to ensure a quality, long lasting job, and it should be the ONLY product to use in the rubber bits of any brake system.

You may already know this but the Lockheed and Girling systems use different shoes that are not interchangeable.

Do one side at a time that way if you can't remember how a spring was attached you can look at the other side, assuming the PO did them correctly last time.
