How is this an argument for the EXISTENCE of minds? If a term is a name only in so far as it designates something and does it rigidly (that is, across all possible worlds in which the 'something' exists), then you've got to prove that minds exist before you can start treating the word "mind" as a name. Basically, you've begged the entire argument in Premise 3.
I mean, step back and look at what you're doing: you're attempting to argue from the fact that there is a term "mind" to the conclusion that minds exist. Does this argument also work with "God"? Does it work with "Santa Claus"? Does it work with "Pegasus"? Obviously not. And your argument doesn't work either.
Aside from your argument never getting off the ground, it's rather apparent that you don't understand Kripke very well.

To ask whether a mind exists is just to ask whether mental phenomenon are ontologically distinct from physical phenomenon rather than being merely descriptively distinct. If they are only descriptively distinct, they can still ontologically identical. The intention of the argument is to show that that mental phenomenon are not merely descriptively different but ontologically different. So:
1) There exists mental events. (e.g qualia, intentionality).
2) If mental events are ontologically identical with physical events, then they are identical in all possible worlds.
3) They are not identical in all possible worlds
C) Mental events are not ontologically identical with physical events.

The mind and brain are distinctively different in that the brain is the generator of ideas/thoughts/mental and the mind is the result, we experience this as consciousness.
This is confusing. I'm not sure what it means to say "The ontological status of X is acknowledged by the mind...." I mean, what does the ontological status of X have to do with anything? Why not, instead, "X is acknowledged by the mind"? At this point, it's unclear which side of the argument you're taking, because what you're saying is, well, muddled.The ontological stautus of X is acknowledged by the mind, however the informtaion itself exists in the brain.
Again, why the 'ontology' talk? Frankly, I have no idea what you're saying. I mean, I can make a good guess, but that's kinda useless, so I won't.The ontology of X maybe identical to the physical existence of X in principal, but so what? All that demonstrates is our ability to form & understand concepts of X.
And still I have no idea which side of the argument you're taking. The only thing I can glean here -- at least that's worth gleaning -- is that cameras store content in the way brains store content. That's a worthy thing to say, but it's just an analogy: it alone doesn't make your case. Are you defending Mind/Brain identity?A video camera can record a moment in time, upon the replay of the video the image will be a exact replica of the time it was recorded, it will be identical in every sense, yet in reality when your watching the video all you'll be doing is experiencing an actaul event, but in a different format.

Obviously you're arguing for the view that the Mind and Brain are not identical, which isn't exactly an argument for the existence of the mind -- as Mind/Brain identity theorists concede the existence of the mind: they simply say that mental processes are brain processes. I think the ones who actually claim that the Mind and Brain themselves are identical are few in number. Nevertheless, shouldn't you have to argue for the existence of qualia? And then explain how qualia are used to undermine the view that mental processes are distinct from brain processes.
There's also the simple rejoinder that mental processes (or mental states) are higher order events. Thus, a complete description of a brain state would include its corresponding mental state, but a complete description of a mental state wouldn't require the neurological description. It wouldn't be a problem, then, to say that mental states don't have neurological properties. It wouldn't make mental events distinction in the relevant way. You'd need an argument, one which you are not giving.
Frankly, I'm not moved by Kripke's argument. But then I'm not moved by anything which so heavily relies on Possible Worlds semantics.

I'm sure you would agree that, if a is identical with b, then they are necessarily identical. Which is just to say it is not possible that, without a, there is still a b (If the morning star is identical with the evening star, then if the morning star doesn't exist, neither does the evening star). But what is meant by "necessary" and "it is not possible"? We can't understand these terms without employing the notion of possible worlds.

I think the problem with Kripke's argument is that, although rigid designators are a nice technical concept, they have no relevance to proper nouns in English.
As you know in rigid designation terminology "a" is a rigid designator if it refers to the same object in every world. Well, that might be a nice technical notion for modal logic (although I'm not sure it is) but does English have any rigid designators? (Because remember rigid designator is a concept of philosophy.)
It doesn't seem that it does. For instance, "water," a proper name, can mean many different things - not just H20. This means that if "pain" and "C-fibre firing" are proper names, then it doesn't follow that they are rigid designators. If they are not rigid designators, the argument fails.
I think it is obvious that we have concepts of modal logic (rigid designators) and concepts of linguistics (proper names/nouns), which don't mean the same.
Perhaps though, rigid designators can be stipulated. So we take what is normally a proper noun in English, and stipulate it some conditions under which it is a rigid designator. For instance, we take "water" and then precisely define it, making it a rigid designator. But then, the "water" used here is no longer a concept of natural language, instead it is a concept of logic and philosophy.
Perhaps.
