Per come è fatta la pagina 116 del MdG, pare che il personaggio non possa avere lo spadone con le chiodature dell'armatura, allo stesso modo in cui non può avere uno spadone con una spada corta...
Le chiodature sono un'arma leggera? (quindi da tenere ad una mano?)

Bè, il problema mi sembra solo formale. Probabilmente RAW è come dici te ma chi leggerà la regola in quel modo?
Comunque non credo sia scritto da qualche aprte che ti lasciano libere le mani salvo in sottinteso questa faq:

Is a character wielding a two-handed reach weapon (such as a longspear) and wearing spiked armor threatening all squares within 10 feet?

Anzi, forse questa ti soddisfa:

Just how and when can you use armor spikes? If you’re using two weapons already, can you use armor spikes to make a second off-hand attack?What if you’re using a weapon and a shield? Can you use the armor spikes for an off-hand attack and still get a shield bonus to Armor Class from the shield? What if you use a two-handed weapon? Can you wield the weapon in two hands and still make an off-hand attack with the spikes? What are your options for using armor spikes in a grapple? Can you use them when pinned? If you have another light weapon, can you use that and your armor spikes when grappling?

When you fight with more than one weapon, you gain an extra attack. (Improved Two-Weapon Fighting and greater Two-Weapon Fighting give you more attacks with the extra weapon.) Armor spikes are a light weapon that can be used as the extra weapon. If you attack only with your armor spikes during your turn
(or use the armor spikes to make an attack of opportunity), you use them just like a regular weapon. If you use the full attack action, you can use armor spikes as either a primary light weapon or as an off-hand light weapon, even if you’re using a shield or using a two-handed weapon. In these latter two cases, you’re assumed to be kicking or kneeing your foe with your armor spikes.
Whenever you use armor spikes as an off-hand weapon, you suffer all the penalties for attacking with two weapons (see Table 8–10 in the PH). When using armor spikes along with a two-handed weapon, it is usually best to use the two-handed weapon as your primary attack and the armor spikes as the offhand weapon. You can use the armor spikes as the primary weapon and the two-handed weapon as the off-hand attack, but when you do so, you don’t get the benefit of using a light weapon in your off hand. You cannot, however, use your armor spikes to make a second off-hand attack when you’re already fighting with two weapons. If you have a weapon in both hands and armor spikes, you can attack with the weapons in your hands (and not with the armor spikes) or with one of the weapons in your hands and the armor spikes (see the description of spiked armor in Chapter 7 of the PH).
When grappling, you can damage your foe with your spikes by making a regular grapple check (opposed by your foe’s check). If you succeed, you deal piercing damage to your foe (see Table 7–5 in the PH) rather than the unarmed strike damage you’d normally deal when damaging your foe with a grapple check. Since you can use armor spikes as a light weapon, you can simply use them to attack your foe. You suffer a –4 penalty on your attack roll when attacking with a light weapon in a grapple (see page 156 in the PH), but if your foe is bigger or stronger than you, this might prove a better tactic than trying to deal damage through a grapple check
because there is no opposed roll to make—you just have to hit your opponent’s Armor Class. You can’t attack with two weapons when grappling, even when one of those weapons is armor spikes (see the section on grappling in Chapter 8 of the PH).
You can’t attack and damage your foe if he has you pinned.
If you break the pin and avoid being pinned again, you can go back to attacking your foe. If your attack bonus is high enough to allow multiple attacks, you might break the pin and then use your remaining attack to damage your foe. To accomplish this, you must first use an attack to break the pin. You can break a pin using the Escape Artist skill, but trying to do so is a standard action for you; once you use the standard action to attempt escape, you can’t make any more attacks during your turn.
