Hi Scott  

Answer to Question 1 (answers Question 2, 3 too). Bkp & Rcvry by Rama Velpuri - Case 8:Recovery with a Bkp control file
<quote>

If you use a backup control file, you need to perform media recovery. Also, Oracle will force you to use the 'using backup controlfile' option.
Once recovery is done, you must start up the database with the RESETLOGS option, and have to take a complete backup of your database. The reason for this is that, Oracle needs to update certain data structures in the backup controlfile before opening the database, and this is done during RESETLOGS. After the database is open, you should immediately take a full online or offline backup of the database because you cannot restore any of the datafiles from before RESETLOGS and try to rollforward.

The book is arguably one of the BEST written on Oracle Backup and Recovery ever.
Better get one.
