Have a read of this:

Ric.

Yes but it doesn't answer all of the questions though,

I didn't say it did - I was just referring you to a very good article on the
subject which, despite not answering all your questions, I though would be a
worthwhile read if you were undertaking the task.

it doesn't say which
order you do the rads in,

That's because there isn't one - that was an unnecesary compication you
added yourself. As the article explains, you are simply trying to make the
resistance across each radiator the same - you will discover which ones have
the most/least resistance when you take your first readings.

nor does it say anything about if you can just
swap the control or LSV. I have a 3 story house, so where you start could
make a difference!

I would say that it probably wouldn't matter which one you use to restrict
the flow as long as you end up with the desired temperature drop but I'm
sure others will disagree!
