questions named.conf

[GanGan]

Hello all,
	
first question :

for have log i add this in my named.conf

logging {
        category "resolver" { "debug"; };
        category "client" { "debug"; };
        category "queries" { "debug"; };
        channel "debug" {
                file "/var/log/named/named.log" versions 2 size 50m;
                print-time yes;
                print-category yes;
                };
        };

It's good ? because my named.log is empty 

second question :

for statistics i add this in my named.conf

statistics-channels {
        inet 91.123.xxx.x port 8053 allow { 0.0.0.0; };
        };
	
I want to see them from anywhere, it's not secure ? (i have not X server
for look with a navigator web in 127.0.0.1 (dedicated server))

third question :

where paste this ? :

recursion no; 
allow-query-cache no; 

in advance, 	
thank you very much for your response

good day
