You know you have 510 when you can get the Effort Ribbon. See "How do I know what my EVs are?"
As for the berries, it says what stat they decrease in their description when you select them in your bag. ("A Poffin ingredient. Using it on a Pokémon makes it more friendly, but also decreases its base [whatever] stat.") But if you must know, Pomeg, Kelpsy, Qualot, Hondew, Grepa, and Tamato decrease HP, Attack, Defense, Special Attack, Special Defense, and Speed, respectively.
