You can transfer the .sav file from the "Battery" file in No$GBA to a DS Flash Kart and replace your original .sav file with the .sav file from No$GBA. Make sure to back up your save file on your flash kart first! If you don't want to spend any money, or don't have a DS Flash Kart, you can't transfer them.

You don't transfer pokémon to Battle Revolution, just copy them. Therefore, they never even leave your DS game.

No you do not
No, Pokemon battle revolution is just for battling. You can obtain Pokemon by transferring them from your DS.
the only way to level up you Pokemon on Pokemon battle revolution is to make a custom pass and then train you Pokemon on your ds game then go back to Pokemon battle revolution and copy 'em again...that's the only way I know

No, to level up your Pokemon in Battle Revolution, you must level them up on your DS game and then copy them back to the Wii game.
