Tradeskill StorageFollow

The collection of resources, and the creation of various components takes up every spec of storage that I have. It seems that we should get something like a craft locker at the wholesaler, or resource specific containers that have more storage slots. Is there any way to manage all this stuff that I dont know about?

Where do you get the 8-slot bags? I've only found 6-slot. Also, how do you make the 10 slot boxes? What is trivial - what level? Can we buy them in game? We're on Neriak server.
