Answer 1

Yes,it is possible to get every Pokemon. you can do that by evolving all Pokemon available in your game then trading the unavailable from other games to yours and evolve them. that's how you complete the Pokedex.

And by DS games, you need to import from the Gba games.

Answer 2

However you'll need to keep up-to-date with events which can really be a pain to miss since most event pokes don't breed and cant be traded.
