Whoa! Ok, let's work this out a bit...
/etc/cron.dail/logrotate should be left alone. You should be creating scripts in /etc/logrotate.d/ OR editing the /etc/logrotate.conf directory. Either way, you should be using the same syntax
I prefer the /etc/logrorate.d because I can safely not touch my conf file and remove/add logs to be rotated without comprimising the others.
Anyway, so onto more good stuff...
/bin/kill ....
That's taking what is possibly your pid of httpd IF you have that directive in your apache/httpd.conf file. However, it's easier to use what you suggested:
/etc/rc.d/init.d/httpd restart
The line:
/bin/kill ...
Is something you might look further into though, just to learn what's going on there. However, it's really OVERKILL and you should have no problem using an easier command to restart apache (the one you suggested).
