All, i was just asked to look into SCCM deployment. I found this nice article online:

My Questions is do I really need all these servers, can I do away with one?
Do i still need to extend the schema if running windows 2008 AD in native mode?

Steps looks ok to me. As far as windows 2008 AD is concerned, that is the upgrade for 2003 AD updating schema will be required for SCOM in 2008 also.

what about the server roles. Do I need two or three different servers? I know for performance it may be a good idea.  Also, there is a step that says
to identify the Schema Master role holder

    Backup the systems state on the Schema Master DC
    Disconnect the Schema Master from the network (just in case it all goes horribly wrong)

Does it mean to disconnect the server where you are updating the schema? once checked successfully you reconnect to network?

The very best step by step guide I have ever seen is this one.

Very accurate, precise and in-depth.

You can run SCCM and SQL on the same server without problem. Its all scallable depends on the number of machines your dealing with at the end of the day.
