2nd your case will be as follow
lets say you have 1 DC and 2 Additional DC
so on one of the two aditional make sure it does not have any FSMO roles
neither DNS nor DHCP
so the scenario is to remove it from the domain(DCPROMO) and install win srerver 2008 on it(CLEAN INSTALLATION) and add it to be a member server, perform (DCPROMO) Now It is additional DC, make it global catalog and give it some time to replicate the data if every thing is OK, transfer FSMO Role to it
and so on if you would like to install also the DHCP AND DNS on it do it
and repeat this way to your servers(IF YOU WOULD LIKE) ,
NOTE
you should prepare yous frost and domain first BEFOR
adprep /forestprep and adprep /domainprep
