I'd go with the A1200. Much faster (even stock) and much more expandibility.
1. Any workbench from floppy will be slow to load. It will be much easier to use on the A1200 because of the processor and additional memory.
2. No. Well, yes but you'd need a BlizzardPPC + BlizzardVision card which cost a lot, and run too hot in a desktop case.
3. Yes. Easier than in the A600. Almost any 2.5" IDE laptop drive will work. I'd suggest something in the 1-2GB range for a stock A1200.
4. Not familliar with the 1942.
