How about this:
1 - There was a First Cause
2a - There was not a First Cause - the universe is infinite and eternal;
2b - There was not a First Cause - the universe just happened.
1 - There was a First Cause
And that is what we call God (not the God of Scripture, however)
There's one suggestion I'd like to make, that I'm wondering which category you'd place into. Is it not possible that the Universe itself is its own cause.
I came up with an interesting idea when thinking about causality the other day. Imagine that you have a piece of string that represents a line of causality. Each point on the string represents an event, and as you go back along the string, each event is caused by the preceding one. Now, try to imagine our Universe comprised of strings like these. Since a cause can have more than one effect, and an effect can have more than one cause, these strings would be interlocking in a highly complex fashion. Since every single little particle in the Universe, and every single bit of energy is part of this web of causality, the Universe itself would seem to be a single block of string, as there are so many of them tightly wound together.
So, we now have a shape that represents the Universe. If you go back to the beginning of the Universe, this shape begins to funnel down into a point. It's at this point that things get interesting. Say there was a God, a First Cause. In this case, when we reach the Big Bang, there will be a line of string extending from the point that is the beginning of the Universe. Now, since this First Cause is self causing, this string must form a closed shape at the other end. What this shape is doesn't matter, the point is that however the line of causality extends back before the Universe, it must be closed off, self-contained at the opposite end to the end where it merges into the Universe. So, if you need to close off the line of causality somewhere, you could if you wanted close it off at the Big Bang. All those lines of string going back could just do a loop.
The consequence of this idea is that the Universe could be the self causing thing. In that case, do you call it the First Cause and therefore God? You could, although it doesn't make any difference what you call it. I think that the word Universe is sufficient, we don't need another word to describe it.

This, thanks to Quantum Physics, gets really wild, because experiment and observation indicates that effects appear to come into existence prior to their causes. Science can demonstrate it, but simply cannot explain it, without abandoning everything else ... so the jury is out...
It's interesting that you mentioned quantum physics, which I think is very interesting to philosophy. You are referring in your post I believe to the fluctuations in the energy of the vacuum of space. which can spontaneously create a proton, an antineutrino and a pion, if you look at it from a linear perspective of time. In that case, you could say that the cause of this creation is the energy fluctuations (the 3 particles need to anhilate quickly though in order to prevent the average energy from being changed and therefore violate the conservation laws).
However, since anti-particles can be thought of as particles moving backwards in time, you could think of this event as a proton and a neutron chasing each other in a time loop, and actually being the same particle. The proton travels forwards in time until it meets a pion, whereby it turns into a neutron and starts travelling backwards in time, until it gives off a pion and starts travelling forwards in time as a proton again. Thought of that way, this event does not have an external cause. The entire loop is self contained.
I think it's a little harsh to say that science "cannot explain it." If science cannot explain it, then that is only because it is difficult to explain in a way that we understand. In terms of actually explaining why it is that this happens, quantum physics does absolutely fine. It doesn't need everything else to be abandoned, at least not eveything else scientific. It does mean though that cetain common sense assumptions are simply wrong. I think the notion that everything has a cause is one that we are gradually going to see to be wrong. Causality is simply a consequence of thinking of time as perfectly linear, as a background against which things are played, which is really only one way of looking at it, and probably not the best. Seeing as both quntum physics and relativity agree that time does not necessarily work in that way, and they are the two cornerstones of modern physics, I think we can fairly safely say that time probably does not work like that.

2a - There was not a First Cause - the universe is infinite and eternal;
The Kalaam Cosmological argument 'disproves' this proposition:
If the universe is infinite, we can never 'go back' to the beginning, the further we go back, the further back the infinite goes ahead of us (infinite regress), but;
If the universe in infinite, the law must hold both ways (infinite procession);
If the universe is infinite, the time between 'moments' is infinite, and can never be crossed - each second would be of infinite duration.
The universe would be composed of an infinite number of moments, and each moment would be infinite, like a fractal - one would travel eternally in time and space, and never get anywhere ... oh, the mind boggles.
Yes, that reminds me of the Xeno's runner and the tortoise problem. You're right of course, it is definitely an incorrect idea. I think the best explanation for exactly why that isn't the case is that time is actually discrete rather than continuous, that you cannot divide time any smaller than the Planck time.

Note:
A complete set of numbers does not exist (one more can always be added to the set).
Just being pedantic here, you mean an infinite complete set of numbers does not exist. There's no shortage of complete finite sets.

True philosophy lies not in an answer, but in the impetus to inquire. As long as the mind inquires about the nature of things, philosophy is alive (even if in error - the Greeks were wrong about a lot of things, but by following the process of inquiry that follows the 'best practice' established by the Greeks, we came to know the truth)
The 'end of philosophy' occurs when we settle for an answer, and too often we call this phase 'the enlightenment' - the 'answer' of the 17thc enlightenment was that by the power of technology man would be freed from a dependence upon nature - we would bring nature to heel - and look at trhe mess that's caused!
So I'm not saying you're wrong, I'm just speculating on the ramifications ...
Nice to see the good old Greek tradition of philosophy continuing. Just to be clear again, I wasn't at any point trying to argue that there cannot have been a first cause, just attempting to refute the argument that there must be one.
I agree that it's never good to reach an answer such that you stop being inquistive altogether, but just to be clear, you're not going too near the post-modernist thoughts that the concept that there is a correct answer out there is wrong are you? We do of course always need to question things, but that doesn't mean that there isn't an objective truth to be discovered, it's just that we can never be 100% sure that we've got it.
