Getting the Hoenn Pokemon is completely optional. Therefore, there is no chronological event that is placed after getting your choice of Hoenn starter. Just try doing some other extra events.
After you get your Hoenn starter and speak to Steven in the Pewter Museum, Steven will be in the Silph Co. bottom floor. He has a Beldum with a Dawn Stone to trade for a Forretress.
Pewter museum!! :D
In order to get Hoenn Starters, you have to have defeated Red at Mt. Silver. Then, go to Silph Co. in Saffron City. Once there, talk to Steven, the Hoenn Champion. Choose one of the colored stones to match up to the type of the Hoenn Starter pokemon.
