What you want to do is the haltdef as well as using echo.
So, something like,
/echo :: $nick :: seteaza modul: +o $opnick (on op event)
/echo :: $knick a fost dat afara de $nick ( $+ $1- $+ ) (for on kick event).
Etc.
So, this is a custom-made /echo, and, since there is a default, if you don't haltdef then you see both. So, after not showing the default, you make your own custom /echo to whatever you like.
Fill in the rest with $banmask $bnick $opnick $knick etc. for the proper events.
