Kevin,
Try exporting your schema owners (code, tables, etc.) as a CYA. When you recreate the db, you can import each schema separately. A pain, but it will save you.

ORA-01578: ORACLE data block corrupted (file # 1, block # 2660)
ORA-01110: data file 1: '/u02/oradata/TIE/system01.dbf'
Since the corruption resides in the SYSTEM tablespace, it seems that the
course of action that should be taken is to re-create the database.

Kevin,
Check DBA_EXTENTS to see what kind of segment is corrupted. If it's a
table or a cluster, you have lost. Otherwise there is a chance to
recover the database. In any case try a full export.
