helppp!

So I've been meaning to go out and buy one of the new games- either Emerald or FireRed or LeafGreen.
But I've got some questions- Does FR/LG only have the first 150 pokemon in the wild, or can you get the new ones too?
Also, what about the wireless adapter? How close do people have to be to connect with someone?

Thanks in advance :).
