I met Bill Doran when he was here in Boise a couple years back for Tree City ComicCon, I have his Foamsmith books. They're a necessity for working with EVA.
About Worbla, after doing a small bucketload of research I found the formula to make it from scratch and know a couple people who can hook me up with half of the materials needed to make it.
On cloth, my beloved gf is a master level costumer per International Costumers Guild rules. My soft parts are lovely although in need of some work atm. My hakama for example are made to resemble traditional hakama including being made of 4.5 yards (yes you read that correctly) of fabric. My shirt was also made from scratch and if my idea, mask purchase, and her measurements are correct I won't need a balaclava.
I will however bug you when it comes to worbla stuff. Here in Idaho the scene as a whole is poor and people using exotic materials..or making armor for that matter is next to nil. Most folks here just can't afford Worbla.
