Correct.

The case I'm thinking of here is if a creature has a damaging attack and also has a secondary attack that causes an incapacitating condition, but the two are not linked. In that scenario, would the full value of the Affliction and the full value of the damage score both add to the OR?
Correct, if it has an Affliction that isn't linked to damage use the full CER.

Correct.

Following the instructions in the article for the Acid Spider I had OR = 5 + 0 + 20 + 3 + 3 = 31, and PR = 6 + 13 + 3 + 16 + 3 = 41. Where did I do wrong?
This is known errata - sorry. The tables have some issues. I've submitted it. But to break it down some:

Offensive Rating
Attack Skill: The Acid Spider's base attack is 15, so 15 - 10 = 5
Affliction: The Acid Spider has nothing applicable here, so 0
Damage: The Acid Spider's main damaging attack is 8 points of impaling damage and 0.5 points of cyclic corrosion damage, so for the impaling attack it's 8 x 2 = 16, while the corrosion damage is 0.5 x 2 = 1 x 10 = 10; total is 26
Fatigue Points: The Acid Spider has an FP of 13, so 13 - 10 = 3
Move: The Acid Spider has a Move of 9, so 9 - 6 = 3

Protective Rating
Active Defense: The Acid Spider has a Dodge of 11, so 11 - 8 = 3 x 2 =6
Damage Resistance: The Acid Spider has DR 4 in all locations and no significant protective traits, so 4 + 4 + 4 +4 / 4 = 4
Health: The Acid Spider has a HT of 13, so 13 - 10 = 3
Hit Points: The Acid Spider has a HP of 26 and no significant recovery traits, so 26 - 10 = 16
Will: The Acid Spider has a Will of 12 and Combat reflexes, so 12 - 10 = 2 + 1 = 3


Thus total OR is 37 and total PR is 32, so total CER is 69.
