best solution for backup with archivelog mode

Hi,
i need some advisors for management backup and archivelog mode.

We make backup of whole database (10g) in offline mode every week on library DLT, and archivelog+flashback is enabled on DB, in this case is possible delete the oldest redolog archived on disk before backup offline?

So, on DLT there are all data and redologs required for restore until last week, and after i can use last redolog (available on ours SAN storage) for recovery DB. It's correct?

Or i need to preserve all redolog files?

thanks!
bye
