Another pluralisation I don't understand is where I might say "we have a long way to go", I sometimes see it written as ".....a ways to go". The a implies singular but ways is plural.

It comes from the other use of the word Lego to mean a single Lego brick, not just the name of the product in general. If you say "a Lego" to mean a brick, then what do you call multiple bricks? Three Lego? Sounds completely weird to me. So it must be a U.S. vs. British English thing.
