I've got almost all of the model bound and weighted apart from the clavicles, spine, and head.

The arms and legs have been quite awkward because my model isn't symmetrical, meaning I haven't been able to mirror the skin weights. As I want as much movement as possible in the Giant's toes (kind of like a chickens foot when it walks), I rigged each of its toes in the same way Alan's skinning tutorials advise to rig JPJ's boots. This seems as though it'll give me the desired movement.
