the shrink will be running but is probably unable to acheive much on the data file as your database is unlikely to have much free space, the log file could be frequently shrinking and growing though. It is safe to uncheck those boxes and stop running those shrinks, I would just make sure the database file growth factors are set sensibly and keep an eye on any database growth for a while.

run a reindex (optimisation) to clean up any fragmentation.
