   What is the difference between the Metaobject protocol described in
the book "The ARt of the Metaobject Prototcol" and the ones used in 
CLOS? Or are they the same?

The description in that book is the latest public definition of the CLOS
MOP.  The MOP designers have been doing some refinements since the book,
but it's probably at least 95% correct.

However, the CLosette *implementation* in that book doesn't conform to the
specification completely.  As the name implies, it's a subset.

Wouldn't comp.lang.clos have been a better place for this question?
