Where are the places Steven Stone is at in Pokemon HeartGold and SoulSilver?

Answer 1

In Pokémon HeartGold and Pokémon SoulSilver, you'll first see Steven Stone as you exit out the Pokémon Fan Club after you have gotten the Clefairy Doll from the guy there. Next you'll see him by the counter in Silph Co. and he'll be asking you which stone choice you want, Red Stone, Blue Stone or Green Stone. Each stone represents 1 of Professor Birch's Starter Pokémon in the Hoenn region, Red Stone for Torchic, Blue Stone for Mudkip and Green Stone for Treecko. Next you'll see Steven in the Pewter Museum in Pewter City. After talking to him there he'll be back in Silph Co. near the entrance and he'll be offering a trade.

is he anywhere else?

You don't really see much of Steven until you go to Kanto. He will come up to you upon exiting the Pokemon fan club house, telling you that Latias(HG) or Latios(SS) is roaming the region. After you defeat Red at Mt. Silver, you can see Steven at the Silph Co. and he will give you the Hoenn starter of your choice.
he is at mt silver after you beat red 10 times
