Sounds like you're on the right track with your plan. I pretty much did what you listed and took a bunch of photos if you're interested in seeing how the process worked for me. Photo albums linked below. I stripped most of the suspension parts with aircraft stripper to remove the majority of the paint, then sand blasted what was left. I bought a cheap blasting cabinet and media from harbor freight for less than it would have cost me to have a shop do it. It took a lot of time though. If I had to do it all now (8 years later) I'd probably just have the powder coating shop blast the parts for me.
For the zinc plated parts I sand blasted those too and send them all to DMCMW. They have a local vendor that does the plating and DMCMW checked to make sure everything was inventoried and nothing was lost. They really went above and beyond considering what they charged which was not much above the vendor's cost. I yellow zinc plated all the large parts and clear zinc plated all the hardware since the chromate layer is a bit thinner so it wouldn't gum up the bolt threads.
I also replaced all the front bushings with poly, and replaced all the rear suspension bushings with new rubber DMCH reproduction parts. While I was in there I also replaced all the rubber coolant hoses, radiator, fuel lines, clutch master and slave, brake master, shocks, lowering springs.... yeah, talk about scope creep. Totally worth it though to just hit all the chassis parts at once and be done.

Note: If you plan to powdercoat the rear links you need to press out the old bushings. The baking process involved with powder will destroy the rubber so it's better to just remove them right away so you don't damage the finish trying to remove the old bushings.
For flaking epoxy on the frame I used sanding discs to remove the epoxy down to bare metal, feathered out the epoxy so there was no hard edge, then applied POR-15 rust preventative paint, POR primer (which helps the top coat stick, and adds coating thickness similar to that of the stock epoxy) and then top coated with Rustoleum Smoke Gray.
