Nice article, however, I would include some reference to the MSDTC and SPN records, for instance:

"If you are installing only the Database Engine, the MSDTC cluster resource is not required. If you are installing the Database Engine and SSIS, Workstation Components, or if you will use distributed transactions, you must install MSDTC. Note that MSDTC is not required for Analysis Services-only instances."

Best regards ...
