Since these are recommendations I assume this must be something that is not yet built? #1 is a horrible recommendation UNLESS they also implement #4. A clustered index on a guid is just plain awful. Since this is the design phase I would HIGHLY recommend you change the name of the table. ASC is a reserved word and you will constantly be fighting with it. Also, a table name should give you an idea of what it contains. This seems like an abbreviation, I would recommend using an actual name instead.

What about MuthalID and ConsumableTypeID. Both of these are also guids. From this structure I would assume those are foreign keys to another table. Do those tables also have these guids as clustered primary keys? How about CreatedBy? This also seems like another guid as a primary key. Can users be deleted from the system? Are they actual deletes or just soft deletes? Do you have the ability to permanently delete after a soft delete? If you use a guid here you either have to make it a foreign key (which will prevent permanent deletes) or use no foreign key and then you have no clue who performed the action once that user is deleted. All you would be left with is a meaningless guid.
