Don't shrink the log file. Take regular transaction log backups (every hour, every 15 minutes, whatever interval is appropriate) and keep the log file large enough to accommodate significant transactions without causing auto growth.

You cannot access a mirrored database except to perform a mirror failover. This is documented in Books Online. Once you fail over, the mirror becomes the principal, and the former principal goes into a mirrored state.
