Yes.

Pretty much, yes. tertiary/unclassified isn't a hard and fast rule.

Not quite:
    "primary A road (green signs)" -> trunk
    "non-primary A road (white signs)" -> primary

> upgraded A road - primary + motorroad

Not really used in the UK. I think that was introduced in Germany.
(Personally I think that was a good decision by the German mappers and I'd
like to see other countries do something similar, albeit co-ordinated with
other nations, rather than always trying to shoehorn in incompatible systems
to the UK-derived classification.)
