1) I get that the file /rdbms/oracle_data/10.2.0/backup/pbh1020/backup_02k9t640_1_1 has the backup of the datafiles but what is in this file /rdbms/oracle/10g2/dbs/c-3969725195-20090314-02?

2) Can I redirect /rdbms/oracle/10g2/dbs to another directory, if so how.

3) I tried running report obsolete on 3/15/09 and as I mentioned I did a full
database backup on 3/14/09. If I have a one day retention period, how come report obsolete does not show me that I can delete this backup.

RMAN> show all;

RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default

RMAN> report obsolete;

RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 1
no obsolete backups found

1) its the control file backup
2) yes - configure your channels properly
3) - you did something wrong

you really really need to read oracle and rman concepts

He got just one backup, how it will expire..!

You don't have a one DAY retention policy, you have a REDUNDANCY of 1 retention policy. If you took another backup you'd see that the first back should be obsolete. What is in backupsets 187-258? I assume you are in archivelog mode and are also backing up the archivelogs?

B&R is something you can not afford to get wrong...as davey23uk mentioned, you really should read over the RMAN docs.
