RE: some datafiles need recovery -noarchivelog -nobackup

Opening the database allowing resetlogs corruption *might* bring them online. Mind you, this database will lose most of oracle's safeties against corruption, so exporting and importing objects to a new database should be the first and only thing you do when you open the database. If backups were taken cold (using begin/end backup or shutting down the database), you should have no problem opening a database with those datafiles, unless SCN has changed for others.

I don't know if this is extreme, but maybe transportable ts can help? Restore a backup (to before the corruption), start that db, export the tablespace that got corrupted and import it back again into your current database.
