I'm not sure why people wouldn't know their reporting chain. It's in the company "phonebook": search for yourself, then follow the "Manager" links...
Expense approval is less clear, because it's not obvious which things your immediate manager can approve and which need to be kicked higher up the chain. But in my experience asking your manager works pretty well. It's possibly I've been lucky with managers.
