Does anyone know what would be cheaper for launching an Apollo and a LEO short-lifespan lab: A 2-launch mission (CLV and CaLV S-IBs) or a 1-launch mission (Saturn-V)?

I suspect there's no easy answer to that question, because it would depend strongly on vehicle production rates, launch rates and other factors.  For example, if you were launching Vs on a regular basis but not using IBs much, then the overheads of maintaining a IB capability divided by a small number of launches make the IB very expensive on a per-launch basis.  On the other hand, if you've just got some old IBs sitting around and are no longer paying for their production, then maybe it's a different story.

In a scenario where you're regularly producing and launching vehicles rather than using up old inventory, then if you've got enough launch business to require several IBs per year, then it's probably cheaper to do it with IBs.  If you've got enough launch business to require several Vs per year, maybe it's cheaper to do it with a V.

Here is a 1967 Apollo Applications Program study final report for a mission to observe the Earth using an Apollo and an attached instrument suite.

On the idea of a CSM and LEM carried together on a 1b:
What if each spacecraft independently completed the ascent to LEO? They'd both have as much delta-v as you like, depending on propellant offload.
