So my question is this. If they now know that it has a volume which is
150+ billion light years across, then it must have occupied a smaller
volume in the past. So how did it manage to expand from virtually
nothing to 150+ billion lightyears across in only 13.7 billion years.

Surely anything that existed shortly after the bigbang could not now
be more than 70 billion lightyears away from its original position.

You're thinking of the speed of light as a limit and at creation time
it wasn't because the physical laws didn't exist until after the
creation bang. Is the first few tiny tiny bits of a second if expanded
at a fantastic rate to nearly the size it is now. Then the Universe
realised it existed and the physical laws came into effect and
expansion continued at a similar rate to today. At least that's my
understanding of what I read about it. I can't remember the title of
the book now but something like 'The Seven Ages of the Universe'.

The 13.7 billion light years that we can see are just the size of our
raisin that we are in the centre of somewhere in a giant Christmas pud
:-)
