A) to write in-universe you have to treat it like you are reporting something that actually happened. You are writing as if you are living in the DC universe. It's not just about not mentioning the comic or the writer. Read pretty much any other page on the wiki to see how it works (for example Swamp Thing (New Earth)).

B) the (New Earth) and (Earth-One) on characters' names are what we call Earth-designations. They indicate which continuity the character comes from. The DCU has been relaunched and altered several times over the years. It is also a Multiverse. There are many versions of Earth in the DCU. Those "Earths" in brackets indicate which of those earths the character comes from.

C) I discourage you from trying to add Batman villains at this time. You are not very experienced as an editor, and we've been at this long enough that THAT page probably doesn't need much added to it.
