Help needed regarding naturalisation

Hi there,

I have few questions and I would be grateful for your kind advice.

1- I have been in the UK for more than 10 years now. I had my ILR on 22/04/08 (WP+HSMP). Does the qualifying period start for naturalisation from 5 years before ILR or 5 years before application for naturalisation (i.e. 22/04/04 or 22/04/03)?

2- my wife arrived in the UK in July 2005 and received ILR with me last April (so will be in the UK for about 4 years by the time I get my passport). My understanding is that she will not be able to apply with me, but can apply after I become a british citizen as a spouse. Is that correct?

3- during the first 2 years of her stay, she was still studying abroad, so spent about 7-8 months of each year abroad. over the last 2 years she has been living here (apart from holidays). she has been absent for the following number of days over the last few years:
July 2005-July 2006: 223 days
July 2006-July 2007: 255 days
July 2007-July 2008: 55 days
July 2008- July2009 (estimated): 91 days

Would she be able to apply this summer based on the discretion rules or would she have to wait for another year.

Thank you for your help
