To address your second question, yes you can "downgrade" from EE to SE, provided you aren't using any enterprise features (as you indicated). I've done this myself. Just install SE in a separate ORACLE_HOME and copy over any config files that are located in your EE ORACLE_HOME directory. Modify any references to the home directory (such as in listener.ora) and run your database from the SE home.
