You can only get it by eBay or by inserting a rom in your computer and hooking it up to Pokemon FireRed or LeafGreen (no idea how you do that.)
you can find it in limewire or other illegal downloadable program but you can easy dowload from limewire just tap Pokemon Black Chaos and that it but look if it's not a viruse
There is a fanmade Pokemon Cursed Black version on cartrige, however there is a rom you can download (i can not find the website again, I will improve the answer when i do find it, sorry)

No unless you can find it on online auction sites such as eBay.
Download VBA, then search for it Google. You'll find the download.
You can't, you can only find that on the white version. You can find Tornadous in Black.
Braviary is only in Pokemon White. Pokemon Black gets stupid Mandibuzz -_-
Vullaby is a version specific pokemon, specific to Pokemon Black. You will need to get someone to trade it to you.
