My question is How do you "unlock" it?  

I reached 400 for this profession..  Where do I find these types of patterns?  Thanks.

(although I do agree that it seems unreasonably expensive to craft)

the right ingredients are :

To do it just gather all the ingredients ad us the discover tool

I have everything but it doesn't let me use them.. the bolts of gossamer and spools of thread don't show up in the 'list' when using the discovery tool..  I'm sure I'm missing something (most likely obvious) but I can't figure out what it is.

This has to be wrong, it simply doesn't make any sense. Apart from that, the equivalent Weaponsmith's boxes require 6 insignias to craft, take for example http://www.gw2db.com/recipes/10916-box-of-berserkers-draconic-armor. Can somebody confirm the mistake please?

yes it is wrong!.

It seems that almost all the recipes on the site for the satchels are wrong (wrong number of insignias).

I was wondering the same thing myself.  Sucks this game is so young.  I'm guessing nobody has tried it.

What does this contain?

11 Berserker Insignia?

6 armor parts + 5 jewels? or else this is realy expensive compared to craft each single pice

I'd like to know the same.  Using 11 insignias makes this significantly more expensive than crafting the 6 pieces individually.  There has to be something else.
