What happens if you execute these individual commands at the command prompt? Diagnostics? ORACLE_SID set correctly?

Are all the required Win Services there? Can you start them manually?

Sure it's the listener? (The ORA- msgs look like the instance isn't running - I could be wrong.) Have you tried lsnrctl?
