How do you "jump" from UK law to EU law for EEA ap

[julianwood]

I would like to ask how and when you actually jump from UK law to EU law.

I was previously on a work permit and married my French wife in France in July 2007. I returned from the wedding on the 22/7/2007 but entered the UK on my work permit which then expired on 19/01/2008. I had then applied for my EEA2 and did travel a few times while it was being considered and was granted entry with a bit of explanation and my EEA2 my EEA2 was eventually granted in 25/07/2008.

During this time I would have moved over from residency based on UK law (WP) to EU law (EU Spouse) and started exercising treaty rights.

When would this have happened so I can work out if I am eligible for naturalisation already or should still apply for an EEA4 first?

Is it when I returned from my wedding on 22/7/2007 as I was married and have rights under EU law but entered with a UK work permit.
Is it when I first entered after my work permit expired and I had applied for my EEA2 or is it when I received my EEA2?

Both of us have been working the whole time and continuously resident with only a few holidays out the UK so if it is from 22/7/2007 I can apply for naturalisation now as its been six years.
