This is because each move has a certain limit of PP it can have. So in other words, you can just make as much PP of a move as you want, it has a limit on how much you can raise the PP by. For example, for moves like Fire Blast can only get their base PP raised to about 7 or 8 or something like that. So basically you cant because you've already raised it to its limit.
hp up is an out-of-battle item that can be used while walking, when used during a battel it will come up with the message you describe.
I don't know any codes but any Pokemon breads with a ditto.
Not that i know of. i dont think there is any.
just train them
You need two DS, one with pearl and one with Heart Gold, then you enter any Pokemon center and go to the union room lady and talk to her. Then talk to the trainer in the union room and select trade.
Yeah, you can get any Pokemon as a shinny, but the chances of it are extremely low.
You must use FIRE type Pokemon or you're in for a long battle. Fighting type is good too but don't use it against Froslass because that pokemons a ghost type and it wont have any effect.
it wont do any good like you can only use it to get darkri in platinum or pearl
Of course!
palkia is only in pearl and dialga is only in diamond
Any kind! Just catch Pokemon and level them up until they're unbeatable. (Electric doesn't effect Rock no matter how strong it is)
One way is to buy loads of Proteins from the poke-mart. BUT soon it will start saying that it wont have any effect.
Palkia is the legendary Pokemon in Pearl, and there is also various Pokemon found in Pearl, but not in Diamond. Diamond has some, that Pearl doesn't have.

Yes.

you get any Pokemon in the game
Pokemon pearl is just like any other Pokemon game : you've got to catch em all
