Transmogrification is changing the appearance of armor and weapons. There are some limitations though, like it has to be a magical item, and you can't change the type of armor. So no making a plate armor set look like cloth
.
It also looks like you need to own the item you want to change to. So if you want to change to a T2 set you need to own it first. It looks like they might add other options later.
As for the Void Storage, it looks like it's meant to store armor sets.
There is a bunch of info on MMO-Champ:
