[Edit]Two things would be nice to have in the armor section:
1) Guidelines for DMs creating new types of armor and shields. Something along the lines of...
- What is armor? Something which takes time to put on.
- What is a shield? Something which can be readied quickly, a full-round action at most.
- To qualify as a new type of armor, it should look and feel different. If you're using the exact same ability list as another armor, you should probably just be using that armor.
- In some cases (specifically skill-based armor), permutations may make sense. One could imagine a version of the "vine shield" composed of mechanical parts and relying on Knowledge (engineering) rather than (nature).
- There should always be a good reason to use an armor. Otherwise you're wasting your time.
I honestly have no idea what your actual design concerns were, so this list is total guesswork.
1) What happens when you wear more than one armor at the same time?
My character may wish to wear a stillsuit under his silksteel while he's in the desert. He definately wants to wear magical clothes along with his adamantine breastplate while he's in the city.
Does only the 'visible' armor function? This makes sense for clothes. Should there be a limit on what types of armor can be worn together? It might make sense to require that an armor must be one or two degrees 'heavier' than the one it is worn over.
The numbers should be self evident: As usual, typed bonuses (i.e. the armor bonus) don't stack, penalties (ACP and ASP) do stack, and one uses the minimum max dex.

I remember some others suggesting the Bone Wall operate like the Bone Armor of Diablo II fame...
Bone Wall: A seemingly random assortment of bones collected into a large shield. With a simple gesture and a necromantic invocation, the souls of dead warriors animate it into a howling cloud which, thankfully, tries to protect you.
- Knowledge (Religion) Ranks Benefit
4: You may use both hands while using the shield, although your attacks take a -2 penalty.
8: The shield bonus applies to incorporeal touch attacks.
13: You gain Positive Energy Resistance equal to the shield bonus of this shield.
18: You take no penalty when using both hands.
Stats: AC+3, ACP 3, ASP 5?
Also, to replace some of the cut/paste in the shields section:
Wooden shield:Made of wood and held together with bands of steel or strips of leather, a wooden shield makes up in shock absorbance what it loses in resilience.
- BAB
+1: Thrown weapons and missiles which miss you are lodged in the shield, you can use them as though you were carrying them.
+5: Your shield acts as a wedge, providing a +2 bonus on disarm attempts.
+10: You can make a disarm check as an AoO against any opponent missing you in melee or attempting to sunder your shield provoke an attack of opportunity from you.
+15: ??? bonus against grapples, as usual?.
