Just FYI, if you're replacing everything, your cost will rapidly approach the cost where you could replace the fronts with disks. If you use a set of FMJ spindles from the local yard and Dr. Diffs ball joint sleeves, you could easily surpass the cost of the disk swap with a full rebuild of the drums.
As far as value, check out Rockauto.com. If they have what you need, you can usually get it pretty cheap. Especially if any of it is on clearance. The bad news there is that if its on clearance, they may not stock it again.
Parts for the 10" front brakes are not easy to find all the time, and finding replacement drums is getting very difficult for any of the 10" SBP drums. Before I started the rebuild, I'd make sure all the drums were in spec. If they're not, you may have an uphill battle...
