Good photo Blaine!
You've got #5 pointing to the correct spot - between the cup and piston.
#2 - I believe that one sits flat-side to the seal (bowl visible) and the spring seats into it. Isn't the spring smaller diameter on the other end?
I've never removed the actuating arm - what did that involve? It always looked to me that the pivot was peened and not removeable.
Also, in case you don't know (I didn't till recently) you can get brake paint - maybe it's called caliper paint - I'm assuming it's impervious to brake fluid.
