It's just like any other front rotor, rear drum brake job.
I'd recommend
www.techna-fit.com for the brake lines. Be sure you use a box ended wrench to loosen and tighten the lines, don't strip the bolts.
Full loaded caliper idea is a solid one. Rebuilding calipers and wheel cyl can be cheap and easy. You can also buy a new slide kit. Just compare the costs and check the condition of the parts you are rebuilding.
Using ceramic pads / shoes is much more affordable and might be an option for you.
Don't buy the part stores cheapest option on rotors and drums. They tend to be crap that doesn't last.
Don't forget to bleed properly when done.
Good luck
