1. Where can I find more general information on the different Slot A models?
You can find the Datasheet for the Slot A Athlons here

2. Should *any* of the models work with a Slot A motherboard?
Basically, yes...there were problems with running the faster(>800MHz, i think) Athlon T-Birds on motherboards with a VIA KX133-chipset, but they should all run just fine on an Irongate(AMD-750) motherboard.
Did you ever upgrade the CPU from a slower or non-T-Bird model?
Did you update your BIOS to the latest version?
Make sure you have set the correct Vcore(CPU-voltage) for your CPU(1.70V for the 750MHz T-Bird).QUOTE
3. (unrelated sort of) Which has better performance - a T-bird with 256k L2 cache, or a non-T-bird model 2 with 512k L2 cache?
The T-Bird will perform better because it has on-die(i.e. integrated into the CPU-core) L2-cache which runs at full core-clock(750MHz in your case).
A non-T-bird has off-die cache(it's located on the PCB inside the cartridge, next to the actual CPU) which runs only at 40% of the core-clock on a 750MHz-part(i.e. 300MHz) - on the faster non-T-Bird models(900MHz and up) it runs only at 33% core-clock.
