brake advice

[bucket]

Finally had enough of living on the edge and have decided to fix the brakes and steering in my 67 c20. The old gal is a farmer special with at least 250k miles. I know the pads are gone cause I can hear metal on metal occasionally. I was planning on replacing pads, cylinders, and flexible lines. Have already replaced M.C. The steering has at least half a turn of play in it. Planning on having to replace tie rod ends at a minimum and maybe the steering box? What else should I expect to replace while I'm at it? Can the drums be serviced or should I replace them? Want to order as many parts as I can before tearing into it.

Thanks all. By the way, this board is great. Awesome resource for our trucks.
