Yes
yes; but one at a time
As far as I know there is no code for key items.

The GameShark code for obtaining all medicine items in Pokémon Emerald is: 82005274 0001. This code will enable you to access all medicine items in your bag. Be sure to use it carefully, as cheating can sometimes cause glitches in the game. Always keep a backup of your save file before using GameShark codes.

No each game has a specific master code and for each master code only certain codes can be put in. Also what game do you need the pokedex code for? If its emerald there is no code for it. Hope this helps
