it's interesting.
What is the meaning of that part of the sentence "None of my friends. . . " ?
Does it mean 'not one ...' isn't 'one' singular? Can 'one' take a plural verb?
As I said earlier, "none" does not always mean "not one." It is not a contracted form of "not one" but comes from an old English word ("nan", I think). It is therefore not always helpful to replace it by "not one" (and actually you couldn't do it with my second sentence since you can't say "one rubbish".
QUOTE
If you say 'no friends' then presumably you would require a plural verb... but 'no one have come..' does that seem right?
Would you say 'one of my friends have a red car' ?
Of course both your examples here require a singular verb but, in my opinion, they merely emphasise the fact that "none" is not a grammatical equivalent of "not one."
QUOTE
the implication now is that 'one' is singular AND plural.
Or does 'none' mean a negative 'all of'?
This is not the implication. "One" is singular, "none" can be singular or plural because it is NOT a contraction of "not one" but a word in its own right.

Out of interest, is there an equivalent in French grammar? Personne ne sont venus personne n'est venu
ok - it is a different language but sometimes parallels help to see the reasoning.
There is no equivalent in French. "Personne" is the translation of "nobody" (or "no one") which would always have a singular verb in English. (Although it does have a plural if you add a tag: eg. "nobody has come, have they?", but this is another topic).
In case you think I'm being influenced by French, English is my mother tongue and most of the grammar books I have at home are aimed at native English speakers, not foreigners learning the language. If you have access to a large Oxford English Dictionary, you will find a paragraph on "none" and which form of the verb to use.
