Joined application for EU couple

[Lukas77]

I hope this is a simple question although couldn't find a clear answer anywhere on the UKBA website.
Me and my wife (both Polish) came to the UK 6.5 years ago and I have been working all this time so I gained my Perm Resident status and have lived here >12months since. Therefore I qualify for naturalization. (btw I haven't got the PermRes card as I know EU citizens don't need to anymore).
Now. My wife only started working 5.5 years ago (so first year stayed at home, looked after our kid).
We were married before coming to UK so I expect that her 1st year when she wasn't working still counts even if she was my dependant.

So the question is: can we apply already (assuming that my status will suffice) or do we have to wait until it's been 6 years since she's started working?
And if we can already - should we include P60s, P45s and what not for both of us or is it enough to only submit mine as the breadwinner?
(we've passed the tests and have all the papers ready just need to confirm so we don't send too early)
Thanks in advance for all the advice

Of course it's up to you to decide what you want, but I am an EU citizen living in UK almost 15 years now, and I have never felt even the slightest need to apply for British Citizenship (by naturalisation).
It is an expensive procedure, and I don't see any benefits for myself coming out of it.

Anyway, if (after this introduction) you want to do it nevertheless, I would advise to apply first of all for a Permanent Residence Certificate (EEA3), because it is free of charge and it checks some of the conditions for naturalisation. And so it reduces the risk that your naturalisation application is refused and you lose the associated fee.
