What does a red shift of 6 physical mean.

It means that the universe now is 7 times larger than when the light was
emitted.

Are you sure you mean universe ?
Does this picture http://antwrp.gsfc.nasa.gov/apod/ap091209.html
proves your point of view ?
What that picture shows is an image of the past and not what
the present situation is.
In fact this picture says nothing IMO about the total Universe.

That is ALL it means, without additional knowledge/
Implying that this last could change your answer ?

A value we measure NOW from light of a galaxy transmitted
in the past.
Does that value mean we can say anything about the present
of that Galaxy (its present position and speed)
IMO the answer is No. (or very little)
Does it mean that we can say anything about the speed
of this Galaxy in the past ?
Also very little.

If we know the cosmological parameters (from other observations), then
we can calculate any distance and any velocity we want at any time we
want.

How do you know that ?
Is this not too optimistic ?
What are the other observations ?
Gravitational lenses ?
