Hi Dave, or anyone interested,
I tried the route I suggested above. The workflow is rather clunky, but for my limited needs I can live with it.
Basically, I:
Used Lightroom to Develop the images, then put the ones I wanted into a Collection and Exported them to a network device.
Used FastStone to sort the images into the order I wanted (very nice slick interface, I thought)
Used FastStone to rename the images, retaining the order that I had sorted them into, as described

Copied the images onto my tablet, and used an image browser to display them in file name order.
Not slick, as I said, but good enough for me to be able to take my holiday pics to show my mum this afternoon.
Dave
