I'd like to clarify some stuffs from MH2 since not a lot of people get to play it.

-Garuga offline quest can be unlocked by connecting your ps2 to a psp with MHportable(MHF1) save on it. It's some sort of an old save bonus but cross system(or capcom just want you to buy portable). The event version is an high rank stat version with an absurd amount of hp, but there's no high rank garuga materials in the game.

-Gold& Silver rath are special because their data couldn't be found naturally inside the game disc (making them 'true' dlc). How this 'special item' works is that certain quests in high rank have the chance(1% each slot) to drop one of the three parts of that special item. Basically you have to grind quests until you get all three, combine to get the item and then keep the item with you until the event shows up.

I'd also like to point out that Gold/SIlver Rath doesn't need HR50 to unlock, you just need the item.

-White fatalis functions the same as above, with the quest you need to grind are elder dragon quests.

-Rajang quest kinda popped out of nowhere and IIRC, a bit too early for your gear at that time as well.
