In a universe that has structure, consciousness is fundamental. Or put another way, in a universe that has structure, information integration is fundamental .

No. The degree (density) of "information integration" manifest as "consciousness", however, is emergent (e.g. multicellular organisms) and not itself "fundamental" (e.g. single cell organisms).
Yes. — 180 Proof
No. If you agree that consciousness is a state of integrated information, then you don't know that the higher forms of it are not, at their most basic level, functioning identically to the lower level forms of it.
You are comparing the highest form of consciousness with the lowest, and concluding that they are not equal. They are not equal, but in fact, human consciousness at its base level functions identically to all other consciousness. At base level, information is integrated - that is all that is necessary. In this universe information is integrated fundamentally. Nothing would exist otherwise.
Consciousness had to evolve and the lowest form of information integration is still present in all forms of consciousness. As the foundation of consciousness, it has to be preserved.
For instance, the minimum information that a mind can integrate is to relate one thing to another ( metaphysics ). Agreed? Without this base function, there can be no consciousness. But this base level of functioning, of relating one thing to another, is ubiquitous in the universe! Such as when we relate a quantum field to an excitation, or a string to its vibration, or a wave to its particle of energy. Structure begins in the relationship of one thing to another. Note, for it to become structure, the information has to be integrated. Structure = integrated information. Matter = integrated information. And integrated information = consciousness - this is what IIT aims to prove with PHI.
Intentional agency (aka "consciousness") is an emergent complex structure irreducible to less complex structures ... or to simple (almost) structure-less structures. (See cellular automata, Conway's "Game of Life", Wolfram's computational irreducibility, etc.) — 180 Proof
Computational automata may not be reducible, but cellular automata certainly is - have you heard of the RNA world? In the real world things are caused, so there is a causal chain for everything's existence. Every step relies upon the integration of information. It is a nonsense to state a cell only becomes functional after it is fully evolved - this is in effect what you are saying!

Do you agree that in order to have structure you need to integrate information?
If you are saying consciousness arises only at a certain density of information, then you would have a definition of consciousness to that effect, that can be tested, and a line in the sand of where in evolution this occurs? If not, then it is only a vague notion that you are expressing.
