Is having a 92MB MDF with a 58MB LDF cobo ok? How do I manage the log to keep things running well? I have jobs in place to trim tables used for history and logging so to keep them trim. I want to make sure I don't neglect the log file.

How and what can I or should I do to keep the log file in check?

The sql script I have running on a nightly schedule is:

declare @DBname varchar(500)
set @DBname = 'E:\Database\backup\PMIS_backup_'+ convert(varchar(MAX), getdate(), 23 ) +'.bak'

BACKUP DATABASE [PMIS] TO  DISK = @DBname
WITH NOFORMAT, NOINIT,  NAME = @DBname
, SKIP, REWIND, NOUNLOAD,  STATS = 10


(recovery mode is simple)
If your database is in FULL or BULK_LOGGED recovery mode, you need to backup your database and log files on a regular basis. If your database is in SIMPLE recovery mode, then you only need to backup your database on a regular basis.
