That looks like more than what I usually need. A couple of other things I do is - write a script to generate some logs and grovel them and email myself a relevant report.
I like to look at lastb command output as well as the bash_history and secure log. In case someone breaks in I might capture what they were doing. Looking at the secure logs will show you who is trying to break in sometimes. Of course I would also agree with the advice of a very strong password.
/usr/bin/lastb
tail -n 400 /var/log/secure
tail -n 200 ~/.bash_history
