How do the Instrument of Accession governing the accession of the State to the Dominion of India affect these provisions?
The Instrument of Accession governing the accession of the State to the Dominion of India specifies certain matters with respect to which the Dominion Legislature may make laws for that State. These specified matters are declared by the President in consultation with the Government of the State, and they limit the power of Parliament to make laws for the said State.

In simpler terms, the Instrument of Accession acts as a guideline for determining which subjects Parliament can legislate on in relation to the State of Jammu and Kashmir. This limitation is set forth in clause (b)(i) of Article 370(1).
