domain contorllers

I know you only need 1 DC to run AD, and 2 if you want redundancy, but I thought FSMO roles need to be seperated like schema master, naming master, PDC-RID Infastructor master, and GC should be on seperate boxes, and for growth if you want to expqand the domain or forest later what is the optimal setup to start with, also with W8K server coming I want to be prepared.

You only need to separate the Global catalog and Infrastructure master roles....  unless all your DCs (could be just the one or lots) are global catalog servers.

So on a single domain you really need 2 DC, not one like it has een recommanded?

I recommend a minimum of 2 DCs in any AD environment, no matter how small.  Darylx has already explained the best practices for when you need to separate the Infrastructure Master FSMO from the Global Catalog role.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Best practice is to have 2 DC's for redundancy, but this is not a requirement and all FSMO roles can exist on a single DC with a Global Catalog.  In a single domain the infrastructure master and global catalog can reside on the same DC.  This is due to the Infrastructure Master not having "anything to do" (MS parlance).

2 DCs on each site is really recommended to provide within-site redundancy bioth the Global catalog, more can be added for futher load balancing and redundancy. Most people leave the FSMO roles where they are and this works well.

As everyone else has said, you need two DCs for redundancy.  You can have a domain with just one domain controller but if that server fails, you're screwed.  You couldn't just install a new domain controller to replace the failed server; you'd have to restore it from backup which is a real pain in practice.
