IP Renumbering

Hello Folks,

I am in the process of performing an IP renumbering on a couple of servers with several domains.

My aim is to limit propogation time as much as possible. What I think I should be doing is reduicng the TTL to a number closer to 5 or 10 minutes rather than two days, but I would like to get validation before I proceed.

Here is basically what I am doing. Original zone:
Code: 
$ORIGIN com.
domain  86400      IN      NS      ns2.nameserver.com.        ;Cl=2
        86400      IN      NS      ns1.nameserver.com.        ;Cl=2
        86400      IN      SOA     ns2.nameserver.com. webmaster.nameserver.com. (
                2002031901 10800 3600 604800 86400 )          ;Cl=2
        86400      IN      A       192.168.0.101   ;Cl=2
        86400      IN      MX      10 mail.nameserver.com.    ;Cl=2
$ORIGIN domain.com.
mail    86400      IN      CNAME   mail.domain.com.       ;Cl=2
*       86400      IN      A       192.168.0.101   ;Cl=2
Becomes (for 10 minute TTL):
Code: 
$ORIGIN com.
domain  600      IN      NS      ns2.nameserver.com.        ;Cl=2
        600      IN      NS      ns1.nameserver.com.        ;Cl=2
        600      IN      SOA     ns2.nameserver.com. webmaster.nameserver.com. (
                2002031901 10800 3600 604800 86400 )          ;Cl=2
        600      IN      A       192.168.0.101   ;Cl=2
        600      IN      MX      10 mail.nameserver.com.    ;Cl=2
$ORIGIN domain.com.
mail    600      IN      CNAME   mail.domain.com.       ;Cl=2
*       600      IN      A       192.168.0.101   ;Cl=2
Is this right, or am I completely on the wrong track here?

Thank you much!
