Do I have the Eaton HO52 drum removal procedure correct?

[Longhorn 70]

I have to do my rear brakes. They are in serious need. I haven't decided whether to do the drums or upgrade to disc. Do I just remove the axles, hub nuts, take the drum off, pound out the studs, replace parts like a normal drum brake job.

If I stick with drums, more than likely have to replace the drums, shoes, seals, hardware kits, wheel cylinders, hoses and studs.

If I upgrade to disc, I'll have to buy brackets, loaded calipers, studs, proportioning valve, hoses and seals. I may also have to mod the ebrake cable. This will be about as much work as the drums.

My questions are.....

Do I want to use car calipers on a truck?
Will the car discs be more reliable than the drums? I know the pads are WAY easier to change than shoes.
Is it better to buy a kit with everything included or get brackets and hit ebay?
