As I see it, some simple arithmetic should solve your problem:

You need 5 levels:
L1 = foundation slab = -34" elevation (assuming 10" slab height)
L2 = foundation wall = -24" elevation
L3 = ground level = 0" elevation
L4 = 4" slab = +4" elevation, set floor thickness accordingly
L5 = wooden wall = +8" elevation
