Answer 1

RowGUID column is used for replication. It allows the replication engine to merge correctly. When replication is enabled this column will be added to tables that do not already have a RowGUID column.

You will not gain anything by using it unless you are planning to implement replication. It is equivalent to setting newsequentialid() as the default value for a column.
