it is annoying having to pay but i'm sure you will get the normal amount of pokemon boxes in the game then if u exceed that you would need to get a subscription to pokemon bank or if you wanted to be able to swap pokemon from X to Y without an extra 3DS then you would get the pokemon bank subscription.
if you dont need the extra space i dont think it will be a requirement to subscribe to pokemon bank to play the game.
Yeah you will need to, Its only from Black, White, Black 2, White 2 but you can transfer from Diamond, Pearl and Platnuim to black, white, white 2 and black 2 then from them move the pokemon to X & Y anyway.
