Note that for LaTeX export, there's no need to explicitly add names to
references -- LaTeX can figure them out for itself from the label alone,
with a little of help.

There are various CTAN packages implementing this, such as cleveref,
hyperref's \autoref command, varioref's \labelformat command... Cleveref
is arguably the most powerful of these, as you can just chuck references
into a \cref command (which replaces \ref):
\cref{figure1,table1,table3,table2}, and it sorts them all out for you,
to produce "Figure~1, and Tables~1 to~3". (Disclaimer: I'm the author of
cleveref.)
