First of all, EEA nationals and their family members get PR, not ILR.
If you and your wife apply together in sept 2014, then there is a high risk of refusal of your wives application. Also keep in mind, there is no appeal. If the application is refused, all your money will be down the drain.
Best way is, you apply when you qualify and get naturalised. Once your wife clocks 5 years, she applies based on PR gained and being married to a British Citizen.
Once again, before submitting naturalisation application, make sure you do qualify 100 percent, because if you do not succeed there is no appeal and all the money is lost.
