As far as the Five Point Plan mentioned above, the only thing I’d change is check the compression FIRST. If there is serious lack of sufficient compression you want to find out why first, before putting too much time, energy, money into fixing it. If the poor compression is caused by bad rings, scored cylinders, cylinder head gasket, etc. all that other work isn’t going to make that much difference in how it runs.
