Elitist Jerks - [PvP] Resilience and other deffensive Stats

I am a PvP focused Mage and this thread is supposed to analyse Resilience and compare it to other defensive Stats. This may of course intressed PvE tanks as well. The goal would be, to find a way to compare diffrent deffensive stats and what they do and bring to your PvP game.
I already posted in the Mage thread, when I had my first ideas concerning this, but decided to put here, to broden the base, since it may intrest many players.
I will keep editing as mistakes and ideas flow in..., man at work!

Up until now, I could not find any good data on resilience. So I would like to ask you for any information and or links concerning resilience.
Most important:

-How does the resilience formula look like?

I lack the items for exstensive testing, but assuming that resilience points translate linear into crit. reduction I come up with:

1 Resilience = 0,025% Crit chance reduction and 0,05% Crit damage reduction

It would be nice if somebody with a lot of resilience gear would test if this holds true for high resilience amounts.

-Does resilience work on EVERY crit. out there?

For example, correct me if I am wrong, DoTs do not crit., so resilience does not hlp there!?

-How does Crit. Damage reduction work exactly?

Will 100% mean no extra crit. damage at all, or will only talented rogues, mages (AP frost), hunters, warriors do crit. damage any more?

From now on, i will try to evaluate resilience, espacially vs. stamina.
I assume 1% crit. raises incoming dps by 1% (so extra crit. damage is assumed to be 100%, this is a very raw assumption, since the crit. damage largly differs in classes and talents) without any resilience, this is well disputable, and one could look closer into it.
I can not come up with a perfect formula, because the two resilience stats change the effectivness of each other. For example, 2000 resilience (oO) would mean a 100% reduction in crit. damage, rendering reduced crit. chance completly useless against many caster classes, in fact only a AP Frost mage can come above 100% extra crit. damage, if "reduced crit damage" works that way, otherwise 100% would mean no extra crit. damage at all.
I did some test calculations and aproximate:

- 1 resilience = 0,03% overall damage reduction

(ca. 0,037 at 40 res, 0,029 at 400, calculated with 20% crit. chance and 100% extra crit. damage base)

I will sum up the flaws of this rule of thumb:

If oponents have a low crit. chance, or do not rely on crits at all (DoTs), resilience may be useless. 300 resilience would translate into 7,5% crit reduction, IF an oponent has less then that...
The "extra crit damage is 100%" assumption:
-physical damage is doubled by default and every physical class has talents to raise it further.
-magical crits do 150% by default but mages can raise that considerably, any AP talent build will lead to 100% crit damage increase.
-pvp warlocks usually do not rely on crit at all, redndering resiliencealmost useless against them.
-the more crit damage reduction you have, the less crit. chance reduction lowers incoming dps (effectivly changing the 100% crit. damage rule)

Further bonus of resilience, that can make up for the flaws:

-resilience reduces volatility of incoming damage greatly, by buffering crit. damage. This is huge in pvp
-since it reduces incoming damage, it helps healers mana in the long run, just like armor and resistances but opossed to stamina.

Stamina vs. resilience, a hit at a rule of thumb:

While resilience reduces incoming overall damage and buffers peak damage, stamina will define the absolut amount of damage you can absorb without any heal, no matter of the dps . we will need some intuitiv aproximations here.
So when you get a steady dps incoming, resilience will hlp. your healer, reducing the damage, while stamina is almost useless, when the max dps drops in, 1% more life and 1% damage reduction will both be on relativly equal terms, basicly making you survive a little longer at a given raw dps amount coming in.
So we keep in mind that resilience gets a bonus for peak damage reduction and the duration game, in the crunch time they would be worth the same.
Using 10k life as base:

-1 stamina = 0,1% more life

So in the crunch time, 3 resilience points are worth about 1 stamina point. But even in this situation, resilience still keeps more edges. Let us look a a extrem example.
