I have two VIP's (for now..) and many services in each VIP.

I recommend to you that use one VIP for each service: one vip for mail 
(pop, smtp, etc.), one vip for databases, one vip for webserver, etc.. 
If you make things wrong when you add a server, you makes down only the 
service in where you add the new server (Think in the ARP problem wit DR 
config... :( ). It's only a personal recommendation.
