Interested, quick question though. While 5th and 6th gen pokemon are clearly not allowed, what about mechanics, abilities and moves? Will dream world abilities or any later-used items be allowed? And what about Fairy typing?

No, no and goodness no, I'm afraid.
The later items and the concept of the dream world aren't produced until the 21st century. Similarly, Fairy typing has yet to be discovered, and the same applies to moves attributed to it.
