Is it true that sharks evolved before trees, roughly 450 million years ago versus 385 million years ago?

Yes. One natural history museum source states sharks appeared in the fossil record before trees existed, and a reference text dates the earliest known sharks to more than 420 million years ago. Together these support the claim that sharks evolved before trees, though the specific 385-million-year tree figure is not given.
