Instead of getting your owner nick hardcoded, you can use a variable for that, along with an alias to set it:

alias setowner { 
  set %owner $$?"What is your owner nick?"
  echo -a * Your owner nick has been set to $+(",$!,") successfully! 
}
on *:text:$($+(*,%owner,*)):#:{
  if (!%f) {
    inc -u3 %f
    msg # $nick $+ , i'll get him for you.
    query %owner $nick wants you on # $+ .
  }
}

And for two lines of message, the use of timer isn't necessary but a trigger control.
