Analyzing the patch

Sorry for the lack of posts, but I need to start analyzing the upcoming Patch 4.0.
Lots of things are changing in my 2 main markets (JC & Inscription) and I need to be sure what items are changed to stockpile effectively.

I will download the PTR later today and will copy at least my JC/BS character (Paladin) and if that went well my Scribe&Alch char (Priest) will get a copy too.
