If you wish to use tagging, then yes all ports would have to support  
it for all devices which are using it. Although in your case it  
sounds fairly simple setup, I would suggest just setting your server  
and voice ports to high priority in your switch and leave it at that.  
Not understanding all the ins and outs of tagging may cause more  
problems than you have now. Most switches with management that  
support vlans will also support port based priority.
