Brian,

If you want to save a little bit of backup space, run the 6pm log backup
just before the full backup. If you run it after, you will have backed up
the 12pm-6pm log activities twice.

Do NOT truncate the log ever, if you want to be able to restore the full
backup and then apply the logs to the full backup. If you were to backup
the database, then truncate the 6pm logs, the 12am, 6am, 12pm log backups
are all useless, since there is an unbridgeable transaction log gap between
the full backup and the first log.
