No you can trade anytime before beating the elite four.
you do not necesarely have to beat the elite 4 to get arceus mostly because you can only get it via hack.
no
You can but you will need action replay you can get a ditto and breed it in scolaceon town but you have to beat the elite 4 and national dex. if i tell you the rest it will be a spoiler!
no
No you don't. I caught it after I beat the Elite Four. You can catch it before or after. It doesn't matter.
You can battle your friend at any time you don't have to beat the elite four.
No. All you have to do is beat the Elite 4.
You can find a ditto by route 218 just outside of Canalave City (the grass) but it is really hard to find so you need a Pokeradar. The yellow patches of grass are usually Ditto. Professor Rowan gives this to you after you beat the Elite 4. There is a 22% chance of a sparkly grass being a ditto
route 7 after beating the elite 4
You have to beat them.
