Gary until you beat him and then you get put into the hall of fame and you become champion
Yes you most definitely can
If you put it on certain Pokemon and trade it, it will evolve.
You can't put a Pokemon in the pokewalker in Pokemon platinum, as the pokewalker was designed for only Pokemon Heartgold & Soulsilver.
AR is used the same on Heartgold as it is with any other game, you put AR in, then it will ask you to put in Heartgold. Follow Instructions xD.
go to the pc
You can't. You have to put Pokemon in the blue thing in the Pokemon center (the PC).
put your Pokemon you want to walk with you first in your party.

yes. just put a male and female Pokemon in the day care and the girl will have an egg. or put a ditto in with an evolved Pokemon
No, only Diamond & Pearl; not even Platinum works on Ranch.
