I grew up and learned to wrench in rural Mississippi and your statement brings back memories. Was a good place for me to learn resourcefulness, especially with the farm wrenching I did and limited budget I had, but maintaining/repairing older autos is so much easier for me these days with the resources of larger cities and the internet at hand.
If I were in your position, as long as you don't find big issues in your inspection, I'd just order a few spare head bolts along with the new head gasket and then button her back up to get it running until you do your full rebuild. I'd replace any seals/gaskets that need it along the way but wouldn't go looking for things to fix since you plan to replace all in the Fall. Typically I'd recommend all new head bolts every time you replace the head gasket but yours are single use and you should be ok as long as you have a few on hand as spares to replace them individually if they fail during the install torque process.
