No. Zecrom is unavailable in Pokemon Black. You will need Pokemon White to get it.
you never really truly finish the game. but you would probably need to finish your national dex, beat the league, beat Cynthia, battle every trainer, and do all events involving Pokemon black (that inclueds the ones Pokemon.com hosts to.)
you need all round pokemon with you so you have one super effective for each. they also need to have a high level, as highe or higher than the elite four.
Yes, it is possible to trade your UK Pokemon from Diamond into the Japanese Pokemon Black version. However, you need to beat the whole game in Pokemon Black & White to be able to trade Pokemon from the other generations.
